The Apostle Peter used the metaphor of a spiritual house to describe the structure that the whole body of believers forms as a collective unit (1 Peter 2:5). Peter stated, “As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ” (1 Peter 2:4-5). The terms Peter used, living stones, spiritual house, and spiritual sacrifices all pointed to the temple that was the focal point of the Jewish religion. Paul touched on this in his letter to the Corinthians when he addressed the topic of divisions in the church. Paul stated:

But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready, for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way? For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not being merely human? What then is Apollos? What is Paul? Servants through whom you believed, as the Lord assigned to each. I planted, Apollos watered, but God gave the growth. So neither he who plants nor he who waters is anything, but only God who gives the growth. He who plants and he who waters are one, and each will receive his wages according to his labor. For we are God’s fellow workers. You are God’s field, God’s building. According to the grace of God given to me, like a skilled master builder I laid a foundation, and someone else is building upon it. Let each one take care how he builds upon it. For no one can lay a foundation other than that which is laid, which is Jesus Christ. Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, straw— each one’s work will become manifest, for the Day will disclose it, because it will be revealed by fire, and the fire will test what sort of work each one has done. If the work that anyone has built on the foundation survives, he will receive a reward. If anyone’s work is burned up, he will suffer loss, though he himself will be saved, but only as through fire. Do you not know that you, are God’s temple and that God’s Spirit dwells in you? If anyone destroys God’s temple, God will destroy him. For God’s temple is holy, and you are that temple. (1 Corinthians 3:1-17)

Paul indicated that building up the body of Christ was a joint effort that no one person could take credit for and said that each person’s work will be tested to see if it was done through human or spiritual effort. Peter may have described believers as living stones because of the effect of the indwelling of the Holy Spirit and the active nature of God’s word in the human heart. The Greek word that is translated spiritual in 1 Peter 2:5, pneumatikos (phyoo-mat-ik-os’) is used to describe things “pertaining to or proceeding from the Holy Spirit. Of persons who are spiritual, i.e. enlightened by the Holy Spirit, enjoying the influences, graces, and gifts of the Holy Spirit” (G4152).

Peter stated:

For it stands in Scripture:

“Behold, I am laying in Zion a stone,
    a cornerstone chosen and precious,
and whoever believes in him will not be put to shame.”

So the honor is for you who believe, but for those who do not believe,

“The stone that the builders rejected
    has become the cornerstone,”

and

“A stone of stumbling,
    and a rock of offense.”

They stumble because they disobey the word, as they were destined to do. (1 Peter 2:6-8)

The word that Peter was referring to was most likely the Ten Commandments that were communicated directly to the Israelites from God on Mount Sinai shortly after they were delivered from bondage in Egypt (Exodus 19-20). The Greek term that is translated word in 1 Peter 2:8, logos (log’-os) was used by the Apostle John to identify Jesus as an eternal being that was present at the beginning of creation. John stated, “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made” (John 1:1-3). Peter indicated that those who disobey the word of God were destined to do so and Paul’s letter to the Ephesians revealed that the destiny of every person was established before the foundation of the world. Paul stated, “Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world that we should be holy and blameless before him” (Ephesians 1:3-4).

Peter indicated that the spiritual house that was being built up by believers was “to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ (1 Peter 2:5). By definition, spiritual sacrifices have to do with God’s divine influence upon the heart. The Greek word “pneumatikos always connotes the ideas of invisibility and of power. It does not occur in the Old Testament or in the Gospels; it is in fact an after-Pentecost word” (G4152). Peter most likely used the term spiritual sacrifices to differentiate between the kind of sacrifices that are made according to our own will and those that are made according to God’s will. When believers offer spiritual sacrifices they are supposed to be doing things that please God. When Jesus was baptized by John, “the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, ‘This is my beloved Son, with whom I am well pleased'” (Matthew 3:16). Likewise, when Jesus was transfigured, “a voice from the cloud said, ‘this is my beloved Son, with whom I am well pleased'” (Matthew 17:5). The Greek word that is translated well pleased, eudokeo (yoo-dok-eh’-o) means to approve of an act and stresses “the willingness and freedom of an intention or resolve regarding what is good” (G2106).

Peter linked the spiritual sacrifices of believers to God’s original plan to deliver the Israelites from bondage in Egypt. Peter said, “But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light” (1 Peter 2:9). After the Israelites entered the wilderness and camped at the foot of Mount Sinai, Moses went up to God and “The LORD called to him out of the mountain, saying, ‘Thus you shall say to the house of Jacob, and tell the people of Israel: You yourselves have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to myself. Now therefore, if you will indeed obey my voice and keep my covenant, you shall be my treasured possession among all peoples, for the earth is mine; and you shall be to me a kingdom of priests and a holy nation” (Exodus 19:3-6). God’s stipulation that the people obey his voice and keep his covenant was what led to the downfall of the nation of Israel. Peter was letting believers know that they were taking the place of the Israelites that were originally called to serve God. The key to our success being obedience to God’s word.

God described the nation of Israel as his “treasured possession” (Exodus 19:5). The Hebrew word cegullah “signifies ‘property’ in the special sense of a private possession one personally acquired and carefully preserves” (H5459). The descriptors “a kingdom of priests” and “a holy nation” suggest that the kingdom of heaven centers around the spiritual sacrifices of God’s people which are dependent on faith in Jesus Christ. Peter said, “So the honor is for you who believe, but for those who do not believe, ‘The stone that the builders rejected has become the cornerstone” (1 Peter 2:7). Jesus also quoted Psalm 118:22-23 after he told the parable of the tenants to the chief priests who wanted to know where his authority came from. Matthew 21:38-44 states:

But when the tenants saw the son, they said to themselves, ‘This is the heir. Come, let us kill him and have his inheritance.’ And they took him and threw him out of the vineyard and killed him. When therefore the owner of the vineyard comes, what will he do to those tenants?” They said to him, “He will put those wretches to a miserable death and let out the vineyard to other tenants who will give him the fruits in their seasons.”

Jesus said to them, “Have you never read in the Scriptures:

“‘The stone that the builders rejected
    has become the cornerstone;
this was the Lord’s doing,
    and it is marvelous in our eyes’?

Therefore I tell you, the kingdom of God will be taken away from you and given to a people producing its fruits. And the one who falls on this stone will be broken to pieces; and when it falls on anyone, it will crush him.”

The Greek word Jesus used that is translated people in Matthew 21:43 is ethnos (eth’-nos). Ethnos is derived from the word etho (eth’-o) which means “to be accustomed”, signifying a custom or a particular way of doing things (G1486). Ethnos has to do with human nature and in the sense of people producing fruits it refers to born again Christians who are walking by the Spirit (Galatians 5:16). Paul contrasted the works of the flesh with the works of the Spirit and said, “But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law” (Galatians 5:22-23).

The Ten Commandments were meant to restrain the Israelites from what Paul described as the works of the flesh. Paul said, “Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, disensions, divisions, envy, drunkenness, orgies, and things like these” (Galatians 5:19-21). The goal was to make the Israelites a holy nation, but without the help of the Holy Spirit. When the LORD came down on Mount Sinai and spoke with the people directly (Exodus 19:11, 20:1), the people were afraid of him and couldn’t process the information he was communicating to them because they were spiritually dead (Exodus 20:18-19). One of the primary issues that prevented the Israelites from connecting with God was that they couldn’t approach him unless they were consecrated, which meant that they had to be cleansed from all of their sins (H6942). In other words, they needed to be sanctified by the Holy Spirit, something that was impossible on a large scale until after Jesus died and was resurrected.

Exodus 20:1-17 records the discourse that took place between God and the children of Israel on Mount Sinai. The Ten Commandments were in essence a brief synopsis of the rules that God expected his chosen people to follow. They were as follows:

1. You shall have no other gods before me.
2. You shall not make for yourself a carved image.
3. You shall not take the name of the Lord your God in vain.
4. Remember the Sabbath day, to keep it holy. 
5. Honor your father and your mother.
6. You shall not murder.
7. You shall not commit adultery.
8. You shall not steal.
9. You shall not bear false witness.
10. You shall not covet. 

After hearing these commandments, the people told Moses they didn’t want God to speak to them directly (Exodus 20:19). It says in Exodus 20:22, “And the LORD said to Moses, ‘Thus you shall say to the people of Israel: You have seen for yourselves that I have talked with you from heaven.” The point the LORD was making was that he had already communicated all that was necessary for him to establish his covenant with the people of Israel. He didn’t need to say anything else to them.

The people of Israel understood that the essence of spiritual sacrifice was contained within the Ten Commandments. Hundreds of years later, when Jesus was teaching his disciples the principles of the kingdom of heaven, he was asked to identify “the great commandment in the Law” (Matthew 22:36). Essentially, what the lawyer wanted to know was which of the Ten Commandments was most likely to be broken by every person and would therefore cause everyone in the whole world to go to hell. Jesus answered, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And a second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets” (Matthew 22:37-40). The two commandments that Jesus identified were similar in that they both focused on loving others. Jesus likely emphasized that we need to love God with all of our being because we tend to hold back certain parts of ourselves in order to keep a safe distance between us and our Creator. The fact that we are expected to love our neighbor as ourselves suggests that in the spiritual realm there are no boundaries between one soul and another. That’s why we must act like we are responsible for everyone’s happiness.

Shortly before his death, Jesus prayed that all believers would be united in the same way that he was with his Father (John 17:11). Jesus prayed, “The glory that you have given me I have given to them, that they may be one even as we are one, I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you have loved me” (John 17:22-23). The Greek words that are translated “become perfectly one,” teleioo (tel-i-o’-o) eis (ice) heis (hice) and o (o) refer to the joining together that Peter and Paul talked about when they said that believers are to be built up (1 Peter 2:5, Ephesians 4:16). The Greek word oikodomeo (oy-kod-om-eh’-o) means to be a house-builder and oikodome (oy-kod-om-ay’) refers to architecture. Peter and Paul likely used these words to convey the process of edification because believers are joined together in a systematic way that results in an enduring structure somewhat like a home that is passed on from generation to generation which can be remodeled as needed. Peter’s depiction of a spiritual house that was built using living stones (1 Peter 2:5) was probably meant to convey the idea of a community that is in constant motion. If you look at the kingdom of heaven as a state of being as opposed to a physical space that has occupants, you might see that spiritual sacrifices are ones that go beyond the boundaries of physical life and deal with the immaterial needs of human beings.

Jesus’ attempt to convince a rich young man that he didn’t need all the possessions he was depending on was most likely hindered by the young man’s image of the kingdom of heaven as a place that was luxurious and designed to provide comfort. Matthew’s gospel states, “And behold, a man came up to him, saying, ‘Teacher, what good deed must I do to have eternal life?’ And he said to him, ‘Why do you ask me about what is good? There is only one who is good. If you would enter life, keep the commandments.’ He said to him, ‘Which ones?’ And Jesus said, ‘You shall not murder, You shall not commit adultery, You shall not steal, You shall not bear false witness, Honor your father and mother, and, You shall love your neighbor as yourself.’ The young man said to him, ‘All these I have kept. What do I still lack?’ Jesus said to him, ‘If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.’ When the young man heard this he went away sorrowful, for he had great possessions. And Jesus said to his disciples, ‘Truly, I say to you, only with difficulty will a rich person enter the kingdom of heaven. Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God.’ When the disciples heard this, they were greatly astonished, saying, ‘Who then can be saved?’ But Jesus looked at them and said, ‘With man this is impossible, but with God all things are possible'” (Matthew 19:16-26).

Jesus indicated there is only one who is good (Matthew 19:17) and suggested that in order to enter the kingdom of heaven one must be perfect (Matthew 19:21). His disciples realized that it would be impossible for anyone to meet God’s standard because giving away one’s possessions went against the very core of human nature. Jesus’ statement, “With man it is impossible, but with God all things are possible” (Matthew 19:26) was meant to point out that God doesn’t expect us to go against our nature, but provides a way for us to do what is humanly impossible. Jesus went on to tell them a parable about laborers in a vineyard in order to show them that it wasn’t a matter of giving things up that hinders people from serving God, but the expectation that God will reward our spiritual sacrifices according to how long or hard we work for him. In the parable, everyone was paid the same wages even though some worked all day and others just one hour. Jesus concluded his parable by stating, “‘Am I not allowed to do what I choose with what belongs to me? Or do you begrudge my generosity?’ So the last will be first and the first last” (Matthew 20:16). In other words, God’s goodness isn’t controlled by our human efforts to please him. It is only when we do God’s will that we receive rewards in heaven.
