…Hilkiah the priest found the Book of the Law of the LORD given by Moses... .And Shaphan read it before the king. Thus it happened, when the king heard the words of the Law, that he tore his clothes. 2 Chronicles 34:14, 18-19
God does not change, but does He change His mind? This is a little tricky, so pay close attention. God told the people His will for them, which was to do good. When the people disobeyed and acted sinfully, God told them that there would be consequences for disobeying His will. God also said that if the people in sin would repent, He would spare them the consequences of their sin.
Did God change His mind, and therefore change? No. It is always God’s will for His people not to sin. It is also God’s will that when people sin there are consequences. It is also God’s will that people in sin repent. It is also God’s will that when people in sin repent, He will deal graciously with them. And it is also God’s will that if those in sin do not repent, He will deal justly with them, which includes His judgment.
God’s will does not change, but people do. Sometimes we repent of our sins and sometimes we do not. God does not change, but our choices determine which aspect of God’s will we will experience: grace or justice.
Make no mistake: It is never God’s will that we sin, but God does use even our sin to accomplish His perfect will!

that may be the best I can do!
