“When God created man (Adam), he made him in the likeness of God. Male and female he created them, and he blessed them and named them Man when they were created. When Adam had lived 130 years, he fathered a son in his own likeness, after his image, and named him Seth.” Genesis 5:1-3

Adam is said to be made in the image of God but after The Fall things have changed such that Adam’s son is not described as created in God’s image but in fallen Adam’s image and likeness. This is a statement of theological significance confirmed in Romans 5 and 1 Corinthians 15.
“Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned… ” Romans 5:12
“For as by the one man’s disobedience the many were made sinners,” Romans 5:19
“Just as we have borne the image of the man of dust,” 1 Corinthians 15:49
Adam’s image includes two things that God’s image did not include. It includes SIN and DEATH. All humans have become dead sinners because we bear Adam’s image. Sin is pollution, which is why Jesus describes the human heart as the source of all kinds of wickedness.
“What comes out of a person is what defiles him. For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. All these evil things come from within, and they defile a person.” Mark 7:20-23
Whilst we are no longer made in God’s image the good news is that Jesus is made in God’s image.
“He (Jesus) is the image of the invisible God, the firstborn of all creation.” Colossians 1:15
“the gospel of the glory of Christ, who is the image of God.” 2 Corinthians 4;4
“He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power.” Hebrews 1:3
The entrance of Jesus Christ into world history was not a surprise. It was part of God’s plan to undo the Fall as prophesied in Genesis 3:15. These words were spoken to Satan.
“I will put enmity between you and the woman and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.” Genesis 3:15
Jesus is the woman’s child. He will be injured (bruised heel). But he (Jesus) will destroy sin and death by crushing Satan’s head.
“But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons.” Galatians 4:4-5
This is important because sin and death are our problem, not God’s. It is on us to put it right, but it is beyond our power to put it right because it is against God. So the powerful God became man to put things right for mankind.
“And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.” John 1:14
Scripture records that:
“For our sake, he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” 2 Corinthians 5:21
“so that by the grace of God he might taste death for everyone.” Hebrews 2:9
Just before His death, Jesus said this astonishing thing in prayer.
“I glorified you on earth, having accomplished the work that you gave me to do. And now, Father, glorify me in your own presence with the glory that I had with you before the world existed.” John 16:4-5
