Man’s thoughts are futile. “The Lord does indeed know human thoughts, knows that they are nothing but a puff of air” (Psalm 94:11 CEB; Ephesians 4:17).
Man’s thoughts often miss the mind of God, like Naaman’s, when he said, “I thought” (2 Kings 5:11).
Man’s thoughts are selfish, like Hezekiah’s, when he was relieved that God’s punishment would not fall upon him, but upon his children (2 Kings 20:19).
Man’s thoughts are abhorrent to God. “The thoughts of the wicked are an abomination to the Lord, but gracious words are pure” (Psalm 15:26 ESV).
Man’s thoughts must be abandoned, because God’s thoughts are so far above and beyond them (Isaiah 55:7-9).
Man’s thoughts focus on the present and on what is material, because they give “no thought of [the] future” (Lamentations 1:9 ESV).
Man’s thoughts are evil, from which spring all sorts of sin and perversity (Matthew 15:19).
Man’s thoughts conclude that money can buy everything, even leading him to try to buy God’s gifts with money (Acts 8:20).
Man’s thoughts are conflicting, always a bad sign (Romans 2:15).
Man’s thoughts belong to the realm of the prince of the powers of the air, “carrying out the inclinations of [his] flesh and thoughts” (Ephesians 2.1-3 HCSB).
So man’s thoughts must be changed by the work of God. We must “let God change the way [we] think” (Romans 12:2 CEV).
Man’s thoughts must be taken “captive to make [them] obey Christ” (2 Corinthians 10:5 ESV).
Then, and only then, will we have “Christ’s way of thinking” (1 Corinthians 2:16 ERV).
