Acts 2:23 (KJV 1900) — 23 Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
God knew of the Jews desire to kill Christ he there determined to use that desire and determine the crucifixion
He did not determine that desire
So in your view that’s where God “learned” of their desire? In your view God was just reacting so something he “learned” from the timeline of creation and found it useful at the time?
Nonsense. Foreknowledge is not “learned” by God. It’s determined by God.
The Crucifixion of Christ was not plan B.
Gods foreknowledge is God’s perfect knowledge of the results of his own action of planning, purposing, and determining All things.
“Known unto God are all his works from the beginning of the world.” (Act 15:18)
