Yes. "God is not a man, so he does not lie. He is not human, so he does not change his mind. Has he ever spoken and failed to act? Has he ever promised and not carried it through?" - Numbers 23:19, NLT. But you know me. I always have something to add... "James 1:17 tells us, “Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows.” And from a website author, "Second, we must make a distinction between conditional declarations of God and unconditional determinations of God. In other words, when God said, “I will destroy Nineveh in forty days,” He was speaking conditionally upon the Assyrians’ response. We know this because the Assyrians repented and God did not, in fact, mete out the judgment. God did not change His mind; rather, His message to Nineveh was a warning meant to provoke repentance, and His warning was successful." - https://www.gotquestions.org/God-change-mind.html
