Where does it say that when God "repents" he changes his mind?
I sure didn't say that? The scriptures say quite explicitly that God does not change his mind. They also say quite explicitly that God has repented. So obviously repent does not mean to "change your mind". As far as it concerns God, it obvoiusly means something different.
Webster defines repent as:
a : to feel regret or contrition b : to change one's mind
I have ALWAYS heard repent used in the second sense or to "change direction" (e.g. God changed His mind.). But in fairness, looking back through these posts are you using the term "repent" in the first sense? (e.g. God felt regret.) Which term are you using? How do you use repent in terms of God?
