In Eden God's plan was damaged, because God wanted to rule the earth through man, and with the disobedience of Adam, the devil took authority and the sad consequences came, but God starts a restoration plan.

GOD SENT HIS SON TO REPAIR THE ORIGINAL PLAN:

A. Christ is the last Adam, 1 Cor. 15: 45.47.
The relationship here is very clear, a first Adam who failed and a last Adam (Christ) who came to restore or repair the damage that occurred in Eden ...
B. Christ came to fulfill the divine purpose, Gal. 4: 4

No matter how big your mistakes or sin have been, if there is a sincere disposition of change, repentance and death to the earthly, God forgives and will use it powerfully for his glory.
