Solomon’s heart was not perfect with the Lord

“For it came to pass, when Solomon was old, that his wives turned away his heart after other gods: and his heart was not perfect with the LORD his God, as was the heart of David his father.” - 1 Kings 11v4

Solomon seemingly had it made. God had made him wiser than any man alive. He had wealth beyond measure, receiving tons of gold every year. He was the king of a powerful nation. He has “everything.”

We would think that if we had everything we would be happy serving God and that we would have no problems. Deep down Solomon had a problem. I Kings 11v1 says that he “loved many foreign women.” The result was that his heart was not “perfect.” He left this sin undealt with. The result is that these foreign wives worshipped their own gods and drew Solomon to worship the false gods as well.

Solomon’s problem was that he did not deal with all of the sins in his life, He never dealt with his problem with women.
It does not matter what the sin is. When we do not deal with sins we open ourselves to all kinds of problems. All sins in our lives have the potential of turning our hearts from God.
