I Kings 11:9 And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel, which had appeared unto him twice,
I think that it is interesting to notice what made the Lord angry. It was that Solomon’s heart turned from the Lord God of Israel to false gods. This anger wasn’t over some petty thing that Solomon did. It was a matter of not loving God and beginning to love other gods.
God had greatly blessed Solomon. Instead of being grateful for what God had done and was doing Solomon began to look to other gods. I think that is most reasonable. I need to remember who is doing great things in my life. I need to always love, honor, and worship the God of heaven. He saved me. He has done all this work in my life.
God wasn’t looking for small things to get angry about. Solomon turned from God to false gods. He quit loving God and started loving false gods.
