Our passage tells us that God is not in all the thoughts of the wicked (Psalm 10:4). It also points out that the thoughts of the wicked “are thoughts of iniquity” (Isaiah 59:7). Obviously, the wicked despise the Lord in their thoughts, but the Lord also despises the thoughts of the wicked. This is why we are told that “The thoughts of the wicked are an abomination to the LORD” (Proverbs 15:26). King David, whom God called “a man after mine own heart” (Acts 13:22), added that the thoughts of the wicked were against him for evil (Psalm 56:5). These wicked thoughts are based upon pride (Psalm 10:4). Conversely, a man yielded to the Lord desires to bring “into captivity every thought to the obedience of Christ” (2 Corinthians 10:5).
“Out of the abundance of the heart the mouth speaketh” (Matthew 12:34). As such, the words that proceed from our mouths provide helpful insights into the condition of our hearts. A man can only deceive with his words for so long; eventually, his speech exposes the reality of his heart's condition. The Bible reinforces this truth when it says, “the words of the pure are pleasant words” (Proverbs 15:26). The Bible also identifies words of praise to God as “pleasant” words (Psalm 135:3; Psalm 147:1). Impure words manifest an unpleasantness. Whereas, a pure heart utters pure words and speaks of the Lord and of His goodness.
