Only a foolish man thinks he can hide anything from the Lord. This includes his thought life. The Lord knows all man’s thoughts (1 Chronicles 28:9) which includes the good (Malachi 3:16) and the bad (Psalm 94:11). David expressed this truth to the Lord when he said, “Thou knowest . . . my thought afar off. . . . For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether” (Psalm 139:2-4). The Lord Jesus Christ often exhibited this capability during His earthly ministry (Matthew 12:25; Luke 5:22; Luke 6:8; Luke 9:47; Luke 11:17). Even the written word of God reveals this ability by being “a discerner of the thoughts and intents of the heart” (Hebrews 4:12).
If asked concerning the origin of thoughts, the average person would swiftly respond with “the mind” or some similar answer. This is not, however, the emphasis of scripture. Overwhelmingly, scripture indicates that thoughts proceed from the heart. This does not mean the beating organ within one’s chest since the scriptures use “heart” in a different manner. When God brought judgment in the days of Noah, He saw that the thoughts of man’s “heart was only evil continually” (Genesis 6:5). In Matthew 15:19, the Bible says, “For out of the heart proceed evil thoughts.” In Luke 24:38, the Lord Jesus asked the disciples, “why do thoughts arise in your hearts?” When one’s thoughts are not according to God’s will, it is a matter of the heart not being right with God.
Of course, God encourages man to think. This may come as a shocker to many but the Lord does not want man to blindly accept information without first giving it thought. During the Lord’s earthly ministry, He often asked men what they thought (Matthew 17:25; Matthew 18:12; Matthew 21:28). His purpose was not because He valued men’s opinions; but, rather, to cause men to think. The problem for the Lord is not that man thinks, but that man thinks and focuses upon the wrong things. God has specific things upon which He wants man to ponder. These involve things that are true, honest, just, pure, lovely, of good report, virtue, and praise (Philippians 4:8). As such, believers should focus their attention upon these righteous thoughts rather than those thoughts espoused by the world, the flesh, and the devil.
As this study has shown, integrity is a matter of the heart, yet it also affects every other aspect of a man’s life. Though men sometimes try to separate an individual’s walk from his true heart’s condition, the Bible reveals the futility of such. Testifying to this truth, the Bible speaks of walking in integrity (Psalm 26:1, 11; Proverbs 19:1; Proverbs 20:7). The Bible says that “by their fruits ye shall know them” (Matthew 7:16, 20) and this principle applies to one’s integrity too. Our passage from Proverbs reveals that as the “just” man walks in his integrity, his children are likewise blessed because of his walk. The secrets of a person’s heart are often unveiled in his walk. Furthermore, a man who walks in his integrity does not fear the judgment of God (Psalm 26:1). Men need integrity of heart, but that integrity must manifest itself in their daily walk.
