OHHH MY..don't you know If Adam and Eve had not FREELY sinned of their own free will there would have been no Crucifixion.
Stop blaming God for creating sin!
Adam was created innocent and unlike his offspring he was able to choose to sin or not sin.. so yes Adams sin was a free choice...but do you think God was surprised? After all He had foreordained Christ and the cross long before He made Adam.
God designed and created Adam, He placed within Adam a set of preferences, so that God knew exactly what Adam would choose in a particular set of circumstances ...God designed the will of Adam.
It was God that set the parameters of Eden ...it was God that gave Adam the rules, it was God that placed the tree in the center of the garden and it was God that placed satan there as well..
The fall was a part of the plan for the glory of God
The cross was a central plan to creation, not an accidental one
What if Christ was never crucified?
