I agree that God didn't WANT Adam to sin (but that He knew that it was inevitable at some point in his life and so He let it happen). And even before creation, the plan of redemption was already ready for future time.
Some people say: "we have a free will, period."
But if we have a total free will (always), then how come Jesus said: JOH 6:44 "No one can come to me unless the Father who sent me draws him, and I will raise him up at the last day.
(We are dead, how can we see or hear if we are dead?)
How come Acts 13:48 says: When the Gentiles heard this, ...all who were appointed for eternal life believed.
ROM 11:7 What then? What Israel sought so earnestly it did not obtain, but the elect did. The others were hardened...
God is calling many people through the Gospel, but only a few get saved, those who are chosen:
MAT 22:14 "For many are invited, but few are chosen."
In response to the post that said: "we have a free will", and "Israel had to reject Him in order for Gentiles to be saved"
Are you saying then that God MADE Israel reject Him in order for the Gentiles to be saved? Or are you saying that Israel was nice enough to reject Him on their own, just by coincidence?
