And before Gen 1:28-29 & 2:15 even before Gen 1:4 the following was, the plan.
Where was the devil, Satan when Gen 2:15 took place? Licking his chops?
Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot: Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, 1 Peter 1:18-20
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. Rev 13:8
Heb 1:2 has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds;
Heb 2:6-8 But one in a certain place testified, saying, What is man (Adam), that thou art mindful of him? or the son of man (Why is this singular, why is it not sons of man), that thou visitest him? Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands: Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him.
Why? Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption. 1 Cor 15:50 - Is it because Adam was created flesh and blood?
Marvel not that I said unto thee, Ye must be born again.
