"And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel." (1 Kings 11:9)
The Scriptures have an interesting commentary on Solomon's life: "When Solomon was old…his heart was not perfect with the LORD his God" (1 Kings 11:4). How is it possible to start well and end sadly?
We Must Guard Our Heart: "Keep thy heart with all diligence; for out of it are the issues of life," Solomon admonished in Proverbs 4:23. The Hebrew word for "keep" is natsar and the main verb for "guard" or "set a watch." Psalm 119 uses natsar 10 times to demand our careful "watch" on our obedience and use of the Word of God. The promise is: "Blessed are they that keep his testimonies, and that seek him with the whole heart" (Psalm 119:2).
Store the Good Treasure: In one of his many confrontations with the Pharisees, Jesus gave several illustrations about the impact of the "heart" part of our nature. Jesus spoke of binding the "strong man," noting that a tree produces the fruit it was grown for, and that snakes are always snakes. Then Jesus makes this observation: "A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things" (Matthew 12:35).
Others Will Try to Turn Your Heart: Jereboam (1 Kings 11-12) led Israel in rebellion against Judah and against God. He "devised of his own heart" (1 Kings 12:33) liturgical practices that "made Israel to sin" (1 Kings 15:34). Peter warns: "Beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness" (2 Peter 3:17).
We must guard our hearts, "for out of it are the issues of life" (Proverbs 4:23). HMM III
