We know from Genesis that we are created in God's image.
Genesis 1:26: Then God said, “Let Us make mankind in Our image, according to Our likeness"
Genesis 1:27: So God created mankind in his own image, in the image of God he created them; male and female he created them.
But then in 1 Corinthians 15:49
Just as we have borne the image of the earthy, we will also bear the image of the heavenly.
So we can know that God's image is not of the earth or earthly.
The first man is from the earth, earthy; the second man is from heaven. 1 Corinthians 15:47
Because Christ IS the image of God.
He is the image of the invisible God... Colossians 1:15
When did/does the true image bearing begin or recommence?
