Will we be fully-divine then, like Jesus? Or was there another reason why He was resurrected?
[
No, we were created as human; our perfect bodies will be these same bodies made perfect and filled with God's glory (1 Corinthians 15:42-47). The second Person of God who became Jesus was never created, though he took on a human body in Mary's womb. Being God, he is eternal. As God, he was resurrected to give us his gift of new resurrection life (Colossians 3:1-4).
1Co 15:42 So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable.
1Co 15:43 It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power.
1Co 15:44 It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body.
1Co 15:45 Thus it is written, “The first man Adam became a living being”; the last Adam became a life-giving spirit.
1Co 15:46 But it is not the spiritual that is first but the natural, and then the spiritual.
1Co 15:47 The first man was from the earth, a man of dust; the second man is from heaven.
Col 3:1 If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God.
Col 3:2 Set your minds on things that are above, not on things that are on earth.
Col 3:3 For you have died, and your life is hidden with Christ in God.
Col 3:4 When Christ who is your life appears, then you also will appear with him in glory.
