So as God viewed all of time ..It was necessary for Him to keep changing His Perfect plans because some of the people refused to follow through on them ??
For instance....God planned for Mary ,a desendant of David ,to carry Jesus and be His mother.But if she said no He had a "backup" plan is that correct?
Does this mean you think God has more than one plan? You're the first person I've ever met who was willing to argue for the idea that God could have a multitude of plans.
Doesn't God's power make you wonder why He can't fulfill his plan even if he has to use a different agent? (That's what he intended to do with Moses when the children of Israel rebelled. He was going to start the same plan over from the lineage of Moses. But it was the same plan.)
What proof from the Bible do you have that God has more than one plan?
