Correct.
How did he pay?
How he paid is why he was made a little lower than the angels.
Why wasn't Adam made equal unto the angels? Why was Adam also made a little lower than the angels?
IMHO Even in Genesis 1:2 this from Eph 6:12 was taking place [ darkness of this age, with the spiritual things of the evil in the heavenly places;] inclusive it that was, the death. Therefore God was about to Ps 104:30 [Thou sendest forth thy spirit, they are created: and thou renewest the face of the earth.] with Adam of flesh and blood to address, the death and the spiritual things of the evil in the heavenly places.
The wages of sin is death, and He tasted that death in our place. The Scripture calls it the Grace of God.
By Grace ye are saved by faith, it is the gift of God...
Man was made a little lower than angels in ability and wisdom. They have not faced the hardships we face in this life, and they cannot be co-heirs with Christ as we will be. They will take a back seat to man in the Kingdom of God.
I heard a preacher once who explained exactly what we wrestle against in Eph. 6:12.
Principalities, are the highest order of rank in Satan's kingdom.
Powers, are the ranks directly below the principalities.
Rulers of the darkness of this world, are the ranks that carry out the orders of the powers.
Spiritual wickedness in high places, are the demon spirits filled with evil and the ability to possess man.
Personally, I believe it was these evil forces that made the "earth without form and void" in Gen. 1:2.
The Scripture makes reference to the tail of the Red Dragon (Satan) drawing 1/3 of the stars of heaven (angels) in Rev. 12:4.
This is a reference that goes back to the dateless past before man was created, but in the context of Rev. 12 they in the future will be cast out of heaven to the earth.
In the past when they took part with Satan, I believe there was war and the result was Gen. 1:2, the earth was all but destroyed.
If this theory is correct, then the creation we read in Gen. 1-2 is actually a recreation of all that was created millions of years ago in the beginning, Gen. 1:1.
