God is particularly interested in what is going on within the heart of man. Specifically, He seeks for, and desires to find, TRUTH.
God wants believers to serve Him in truth. In fact, it is this very issue that will determine “of what sort” our work is at the judgment seat of Christ.
When men choose to reject the truth, God tends to withhold further truth from them. The result is spiritual and intellectual darkness.
Thoughts do not have to be wicked in order to be troublesome. Any thought contrary to faith will eventually cause a man to stumble. In Genesis 20:11, Abraham’s thoughts hindered his faith. He perceived that the fear of God was not in Gerar and decided to lie about the identity of his wife in order to insure his personal well-being. Rather than trusting God, he trusted his thoughts. Another example is Naaman. He refused to wash in the Jordan River because he thought that the prophet should have recovered his leprosy by coming out, calling upon the name of the Lord, and striking his hand over the place of leprosy (2 Kings 5:11). When a man trusts in his own thoughts over the words of God, that man shows a complete disregard for truth.
