I must be dense. I don't see how this leads to conclude that God changed his mind. I greatly regret that my son took some wrong actions when I gave him certain choices too, but it doesn't mean I would have done things differently had I known the outcome.
I think we have a language barrier regarding regret, repent etc. We cannot accept that God can be sad about the results and actions of his creation.
re: my post 167. your review and opinion would be valued regarding my argument and logic.
The implied question in 1 Samuel 15:11 ""I greatly regret that I have set up Saul as king, for he has turned back from following Me, and has not performed My commandments."
is not if God changed his mine, it is did God had perfect foreknowledge or did Saul's freewill make the outcome unknown to God
