The bible assures us of the following things about God’s unchanging nature. God will not change towards us with his promises. Any seeming change in God’s dealings is from humanity point of view not God. Every time God changed his mind it was in favour of man not against man. The scripture tells us about God relenting or repenting of what he said he would do, each instance is in regard to punishment, it is never a case of God promising to do something ood and then changing his mind. His promises to us will not be broken.
