Genesis 1:26 tells us that the human race came into existence through the creation of a single man who was called Adam. It states, “Then God said, ‘Let us make man in our image, after our likeness.’” The Hebrew word that is translated image, tselem (tsehˊ-lem) “means image in the sense of essential nature: human nature in its internal and external characteristics rather than an exact duplicate…God made man in his own image, reflecting some of His own perfections: perfect in knowledge, righteousness, and holiness, and with dominion over the creatures (Genesis 1:26). Being created in God’s image meant being created male and female, in a loving unity of more than one person (Genesis 1:27). It also says in Genesis 1:26 that we were created after God’s likeness. The Hebrew word dᵉmuwth (dem-oothˊ) means “resemblance” and more concretely, “model, shape.” When we see family members, we sometimes notice a family resemblance. Family members look like each other because of the genetic code they share; so you might say that God’s creation of human beings was the result him replicating his own DNA, similar to a man and woman conceiving a child.

The conception of Jesus was possible because God and humans have similar natures and a genetic makeup that enables them to be joined together into a single entity. It says in Luke 1:30-35:

And the angel said to her, “Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end.”

And Mary said to the angel, “How will this be, since I am a virgin?”

And the angel answered her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy—the Son of God.

It says in Hebrews 1:3 that the Son of God is “the exact imprint of his nature.” Jesus is the essence (G5287) of God, an exact copy of his character (G5481), represented in the form of a human being. Jesus told his disciple Philip, “Whoever has seen me has seen the Father” (John 14:9).

The announcement of Jesus’ birth indicates that he was not just the Son of God, but also the anticipated Messiah that would save God’s people from the guilt and power of sin and from eternal death (G4990). Luke 2:11 states, “For unto you is born this day in the city of David a Savior, who is Christ the Lord.” When he was presented at the temple, shortly after his birth, a man named Simeon spoke about Jesus’ role through the Holy Spirit. Luke says about Simeon, “And it had been revealed to him by the Holy Spirit that he would not see death before he had seen the Lord’s Christ. And he came in the Spirit into the temple, and when the parents brought in the child Jesus, to do for him according to the custom of the Law, he took him up in his arms and blessed God and said, “Lord, now you are letting your servant depart in peace according to your word; for my eyes have seen your salvation that you have prepared in the presence of all peoples, a light for revelation to the Gentiles, and for glory to your people Israel’” (Luke 2:26-32). Simeon said that he had seen God’s salvation (Luke 2:30). The Greek word that is translated salvation, soterion (so-tayˊ-ree-on) means “a savior, deliverer. Delivering, saving, bringing salvation” (G4992).

The idea that Jesus’ birth brought salvation into the world is expanded on in Titus 2:11-14. Paul wrote to Titus, “For the grace of God has appeared, bringing salvation for all people, training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works.” The training that Paul was referring to was the training of a child, “i.e. educate, or (by implication) discipline” (G3811). According to Paul, salvation is a training process that humans go through in order to become more like God. It involves discipline that causes us to “renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives” (Titus 2:13).

The way that Jesus educated or you might say disciplined his disciples was by demonstrating for them appropriate behavior. The night before he was crucified, Jesus washed his disciples’ feet in order to teach them how sanctification works. John tells us:

Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going back to God, rose from supper. He laid aside his outer garments, and taking a towel, tied it around his waist. Then he poured water into a basin and began to wash the disciples’ feet and to wipe them with the towel that was wrapped around him. He came to Simon Peter, who said to him, “Lord, do you wash my feet?” Jesus answered him, “What I am doing you do not understand now, but afterward you will understand.” Peter said to him, “You shall never wash my feet.” Jesus answered him, “If I do not wash you, you have no share with me.” Simon Peter said to him, “Lord, not my feet only but also my hands and my head!” Jesus said to him, “The one who has bathed does not need to wash, except for his feet, but is completely clean. And you are clean, but not every one of you.” For he knew who was to betray him; that was why he said, “Not all of you are clean.” (John 13:3-11)

“By his statement, ‘If I do not wash you, you have no share with me,’ it seems that the Lord was referring to the necessity of regular spiritual cleansing to remain in fellowship with him. Jesus did not say, ‘you have no share in me (en [1722] emoi), which would indicate Peter lacked salvation, but ‘you have no share with me (met’ [3326] emou), meaning Peter would have no communion and fellowship with him. Christians need constant cleansing and renewal if they are to remain in fellowship with God” (note on John 13:8).

Jesus went on to explain to his disciples the reason why he, the Creator of the human race, became a human being. John said:

When he had washed their feet and put on his outer garments and resumed his place, he said to them, “Do you understand what I have done to you? You call me Teacher and Lord, and you are right, for so I am. If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. For I have given you an example, that you also should do just as I have done to you. Truly, truly, I say to you, a servant is not greater than his master, nor is a messenger greater than the one who sent him. If you know these things, blessed are you if you do them. (John 13:12-17)

Jesus wanted his disciples to understand that sanctification was not something that they could achieve independent of God. Sanctification is a process that involves service. Jesus demonstrated how to do it so that his disciples would have an example to follow. God was no longer just telling the people of Israel what they needed to do. Jesus showed the people how to do it by doing it himself.

Paul told the Philippian believers, “Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross” (Philippians 2:4-8). Paul said that Jesus found himself in human form, making it sound as if Jesus woke up one day and discovered that he had been changed into a human being. The Greek word that is translated found, heurisko (hyoo-risˊ-ko) is “spoken of computation, measurement, to find, figure out a value, a distance, etc. (Acts 19:19; 27:28). To find out mentally, i.e. to invent, contrive, to find a way to do something” (G2147). When God formulated his plan of salvation, it seems likely that it was based on him finding a way to manifest himself in human form. The good news for us is that we don’t have to find a way to do the reciprocal. We were created in the likeness of God, all we have to do is believe that Jesus’ death on the cross is able to restore the divine image within us.
