Psalm 99, which is titled The LORD Our God is Holy, begins with a tribute to God’s exalted position in the world. Psalm 99:1-5 states:

The Lord reigns; let the peoples tremble!
    He sits enthroned upon the cherubim; let the earth quake!
The Lord is great in Zion;
    he is exalted over all the peoples.
Let them praise your great and awesome name!
    Holy is he!
The King in his might loves justice.
    You have established equity;
you have executed justice
    and righteousness in Jacob.
Exalt the Lord our God;
    worship at his footstool!
    Holy is he!

The Hebrew word that is translated holy, qadowsh (kaw-dosheˊ) “is often used to refer to God as being inherently holy, sacred, and set apart (Psalm 22:3[4]; Isaiah 6:3; 57:15); and as being free from the attributes of fallen humanity (Hosea 11:9). Therefore, in the Old Testament, God is accorded the title ‘The Holy One of Israel’ (2 Kings 19:22; Psalm 78:41; Isaiah 17:7; Jeremiah 50:29). As such, God instructed that humanity should be holy because He is holy (Leviticus 11:44, 45; 19:2)” (H6918).

God indicated that the way that people were to become holy was through consecration. He said to the Israelites, “For I am the LORD your God. Consecrate yourselves therefore, and be holy, for I am holy. You shall not defile yourselves with any swarming thing that crawls on the ground. For I am the LORD who brought you up out of the land of Egypt to be your God. You shall therefore be holy, for I am holy” (Leviticus 11:44-45). On another occasion, God made it clear that all the people of Israel were to be holy (Leviticus 19:2) and later added that he is the one that sanctifies us (Leviticus 20:8). God said, “You shall be holy to me, for I the LORD am holy and have separated you from the peoples, that you should be mine” (Leviticus 20:24).

In his letter to the Ephesians, the Apostle Paul explained the process that God established before the foundation of the world to make his chosen people holy. Paul said:

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. In love he predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. (Ephesians 1:3-10)

Paul continued his explanation using the analogy of a husband and wife’s relationship to each other to illustrate how sanctification works. Paul said:

Wives, submit to your own husbands, as to the Lord. For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Savior. Now as the church submits to Christ, so also wives should submit in everything to their husbands. Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. (Ephesians 5:22-27)

The process of sanctification is focused on the unification of Christ with his church. Paul said that we need to submit ourselves to Christ, so that his word can make us holy. The Greek word that is translated sanctify in Ephesians 5:26, hagiazo (hag-ee-adˊ-zo) means “to make holy” and when “spoken of persons: to consecrate as being set apart of God and sent by Him for the performance of His will” (G37). Hagiazo is derived from the word hagios (hagˊ-ee-os) which is translated as both holy and saints throughout Paul’s letter to the Ephesians (1:1, 4, 13, 15, 18; 2:19, 21; 3:5, 8, 18; 4:12, 30; 5:3, 27; 6:18). When the word saints is used in the New Testament, it is referring to someone that has been purified and sanctified by the influences of the Holy Spirit. “This is assumed of all who profess the Christian name” (G40).

The term saints is also used in the Old Testament. The Hebrew word qadowsh (kaw-dosheˊ) which is usually translated holy is translated saints in Deuteronomy 33:3 in the King James Version of the Bible. Qadowsh is also translated as saints or holy ones in Psalm 16:3, 34:9 and 89:5, as well as in several books of prophecy (Daniel 8:13, Hosea 11:12, Zechariah 14:5) and in the book of Job (5:1; 15:15). Zechariah’s prophecy of the coming Day of the LORD seems to link together both the Old and New Testament saints and the unification of Christ with his church. Zechariah proclaimed:

Behold, the day of the Lord is coming,
And your spoil will be divided in your midst.
For I will gather all the nations to battle against Jerusalem;
The city shall be taken,
The houses rifled,
And the women ravished.
Half of the city shall go into captivity,
But the remnant of the people shall not be cut off from the city.

Then the Lord will go forth
And fight against those nations,
As He fights in the day of battle.
And in that day His feet will stand on the Mount of Olives,
Which faces Jerusalem on the east.
And the Mount of Olives shall be split in two,
From east to west,
Making a very large valley;
Half of the mountain shall move toward the north
And half of it toward the south.

Then you shall flee through My mountain valley,
For the mountain valley shall reach to Azal.
Yes, you shall flee
As you fled from the earthquake
In the days of Uzziah king of Judah.

Thus the Lord my God will come,
And all the saints with You.

It shall come to pass in that day
That there will be no light;
The lights will diminish.
It shall be one day
Which is known to the Lord—
Neither day nor night.
But at evening time it shall happen
That it will be light.

And in that day it shall be
That living waters shall flow from Jerusalem,
Half of them toward the eastern sea
And half of them toward the western sea;
In both summer and winter it shall occur.
And the Lord shall be King over all the earth.
In that day it shall be—
“The Lord is one,” And His name one. (Zechariah 14:1-9, NKJV)

Zechariah’s vision indicated that the LORD would come to the earth “And all the saints” with him (Zechariah 14:5). This is what is referred to in the Bible as the second coming of Christ, the appointed time when he will return to the earth and will reign over the entire world. The period of time in between Christ’s first and second coming is sometimes referred to as the Church Age, a period of time when the Gentiles will gain equality with the Jews and will enter God’s kingdom on the same basis, by grace through faith (Ephesians 2:8). Paul talked about the Jews and Gentiles becoming one in Christ in his letter to the Ephesians. Paul said:

And he came and preached peace to you who were far off and peace to those who were near. For through him we both have access in one Spirit to the Father. So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the same household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit. (Ephesians 2:17-22).

Paul used the Greek word hagios (hagˊ-ee-os) to refer to both “the saints” and the “holy” temple that was being built together into a dwelling place for God (Ephesians 2:19, 21). The Greek word that is translated are being built together, sunoikodomeo (soon-oy-kod-om-ehˊ-o) means “to construct, i.e. (passive) to compose (in company with other Christians, figurative)” (G4925). Sunoikodomeo is derived from the words sun (soon) which denotes a union “i.e. by association, companionship, process, resemblance, possession, instrumentality, addition etc.” (G4862) and oikodomeo (oy-kod-om-ehˊ-o). Figuratively, oikodomeo means “to build up, establish, confirm. Spoken of the Christian Church and its members who are thus compared to a building, a temple of God, erected upon the one and only foundation, Jesus Christ (cf. 1 Colossians 3:9, 10) and ever built up progressively and unceasingly more and more from the foundation” (G3618).

The Greek word oikodomeo is sometimes translated as edify and is related to the word oikodome (oy-kod-om-ayˊ) which means “architecture that is (concretely) a structure” (G3619). Oikodome is usually translated as edifying or edification and was used by Paul to describe the process that the Church is going through in order to reach maturity and unification with Christ. Paul talked about this process in his letter to the Ephesians under the topic of unity in the Body of Christ. Paul said:

And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes. Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love. (Ephesians 4:11-16)

Edification may be a type of joint sanctification in which each member of the Body of Christ that is continually being added contributes to the collective state of the whole. Hebrews 12:12-14 indicates that holiness is the final state of the Church and a necessary condition for the Lord’s return. It states, “Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. Strive for peace with everyone, and for the holiness without which no one will see the Lord.” The Greek word that is translated holiness, hagiasmos (hag-ee-as-mosˊ) is derived from the word hagiazo (hag-ee-adˊ-zo) which means to make holy (G37) and refers to the resultant state of the process of sanctification (G38).

The book of Leviticus teaches us that holiness is a state that can be transferred between things and people. The opposite of holiness is to be defiled which resulted from coming in contact with something that was unholy or profane. Leviticus 21:7 and 22:1-3 indicate that a woman whose virginity had been violated entered a state of defilement (H2491) and was cut off from the LORD’s presence. Numbers 5:1-3 states that anyone that was defiled had to be put outside the camp, “that they may not defile their camp” because the LORD resided there. In the same way that something or someone could become defiled; things and people could be made holy by coming in contact with something that had been consecrated to the LORD. Exodus 29:36-37 states, “Also you shall purify the altar, when you make atonement for it, and shall anoint it to consecrate it. Seven days you shall make atonement for the altar and consecrate it, and the altar shall be most holy. Whatever touches the altar shall become holy.”

In addition to the altar, the sanctuary of the tabernacle, all the utensils that were used for sacrifices, the priests, and even the priests’ garments were considered to be holy things (Exodus 30:29; Leviticus 6:18, 27). The transfer of holiness from one object to another was connected with physical touch, but the Hebrew word that is translated touch, naga (naw-gahˊ) is sometimes used figuratively in the sense of emotional involvement and also sexual contact with another person (H5060) suggesting that the physical contact might have something to do with intimacy. Jesus often touched the people that he healed and on at least one occasion had physical contact with a man who had leprosy, a condition that defiled a person (Leviticus 13:3). Matthew tells us that when Jesus “came down from the mountain, great crowds followed him. And behold a leper came to him and knelt before him, saying, ‘Lord if you will, you can make me clean. And Jesus stretched out his hand and touched him, saying, ‘I will be clean.’ And immediately his leprosy was cleansed” (Matthew 8:1-3). The Greek word that is translated touched in Matthew 8:3, haptomai (hapˊ-tom-ahee) is properly translated as “to attach oneself to” (G680). Haptomai, used figuratively, means “to have sexual intercourse” (1 Corinthians 7:1), so the sense of intimacy seems to apply to the circumstance of Jesus healing the leper.

Isaiah’s vision of God’s throne room validates Jesus’ inherent holiness. Isaiah wrote:

In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said:

“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory!” (Isaiah 6:1-3)

Isaiah referred to Jesus as the “Holy One” and said of him, “For your Maker is your husband, the LORD of hosts is his name; and the Holy One of Israel is your Redeemer, the God of the whole earth he is called” (Isaiah 54:5).

“God’s presence is what makes any place, anything, or anyone holy (Exodus 3:5)” (H6944). One of the distinct characteristics of the Israelites’ camp while they were traveling to the Promised Land was that the Lord was dwelling in their midst (Numbers 5:3). Numbers 7:89 states, “And when Moses went into the tent of meeting to speak to the LORD, he heard the voice speaking to him from above the mercy seat that was on the ark of the testimony, from between the two cherubim; and it spoke to him.”

Moses’ interaction with the LORD involved a type of emotional involvement that might be considered to be intimacy or attaching oneself to another person. It says in Exodus 33:11 that God spoke “to Moses face to face, as a man speaks to his friend” and in Exodus 34:29 it states, “When Moses came down from Mount Sinai, with the two tablets of the testimony in his hand as he came down the mountain, Moses did not know that the skin of his face shone because he had been talking with God.” The rays of light that were coming from Moses’ face bare a resemblance to the description that Matthew gave of Jesus’ transfiguration. Matthew recorded, “And after six days Jesus took with him Peter and James, and John his brother, and led them up a high mountain by themselves. And he was transfigured before them, and his face shone like the sun, and his clothes became white as light. And behold, there appeared to them Moses and Elijah, talking with him” (Matthew 17:1-3).

The Greek word that is translated transfigured in Matthew 17:2, metamorphoo (met-am-or-foˊ-o) appears to be related to the process of sanctification. Metamorphoo is derived from the words meta (met-ahˊ) which denotes accompaniment (G3326) and morphoo (mor-foˊ-o) “to fashion.” “Morphoo refers, not to the external and transient, but to the inward and real; it is used in Galatians 4:19, expressing the necessity of a change in character and conduct to correspond with inward spiritual condition, so that there may be moral conformity to Christ” (G3445). Paul used the word metamorphoo in his second letter to the Corinthians in connection with the veil that Moses put over his face to cover the light that shone from it (2 Corinthians 3:12-16; Exodus 34:33-35). Paul said, “And we all, with unveiled face, beholding the glory of the Lord, are being transformed (metamorphoo) into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit” (2 Corinthians 3:18).

Paul expanded on his discussion of transformation in his letter to the Romans. Paul wrote:

I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. (Romans 12:1-2)

According to Paul, the renewal of the mind was the key to sanctification. Paul said that we are not to be “conformed to this world” but transformed by the renewal of our minds (Romans 12:2). The Greek word that is translated renewal, anakainosis (an-ak-ahˊ-ee-no-sis) stresses “the continual operation of the indwelling Spirit of God” (G342) which is commonly referred to as the Holy Spirit or hagios (hagˊ-ee-os) pnuema (pnyooˊ-mah) in the Greek.
