When God created Adam, he had the propensity to sin. Adam was not perfect when created, he was innocent.
To understand Adam we need to see Adam as Paul presents Adam in 1 Cor. 15:42-46.
Adam, the natural man, was literally "bound" with dishonor, weakness and corruption in his natural body which body was "bound" for death, with the intents of a Permanent Spiritual Body, a Second Man, A LAST ADAM. Paul describes this as Gods Way, first the natural, then the Spiritual.
Even the scriptures themselves are put together in this way, first the natural, then the Spiritual.
Jesus, God Himself in the flesh, conformed to this standard by having a natural body which DIED, and then a Glorified Body. The "exception" standard with Jesus is that He Had No sin, no corruption, no dishonor, no weakness, because we are talking God Himself in flesh here. There is the difference.
There is a notion that God had to have a death sacrifice in order to save us. This is a false notion. The entire exercises of Jesus' death, shedding of blood, glorification, is the construct of the FINAL SPIRITUAL BODY, which Body we ALL who believe have our part in. It is the account of His Body.
Hebrews 2:14
Forasmuch then
as the children are partakers of flesh and blood,
he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
With God, it was not just 'all talk no action' on His Part. Just as we are formed in a natural body, bound for death, on our way to His Body, God Himself took part in this matter, Himself, being a natural man, dying a very horrendous but DIVINELY PLANNED death, and a likewise Glorious Resurrection.
IT is problematic for us to perceive, presently, our part in His Body. It is presently HIDDEN, Purposefully, Divinely hidden. We do not see the 'unveiling' of the completed Body until it's completed and ALL THE COMPONENTS are likewise completed.
Colossians 3:3
For
ye are dead, and
your life is hid with Christ in God.
Hebrews 11:40
God having provided some better thing for us,
that they without us should not be made perfect.
In short, there is a Divine Construction Project that has been going on, since Day 1 of mankind.
