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.
This verse, apart from John 3:16, may be the most recognized and certainly the most quoted verse by those who have little concern for God or the things of God. Matthew 7:1 also happens to be one of the most misinterpreted and misapplied verses in all of scripture. This verse is abused by non-Christians as well as those living a carnal lifestyle. Non-Christians do not want to be held to any biblical standard while carnal Christians attempt to use the verse to avoid having judgment passed upon them and their questionable actions. The spiritual Christian knows that the context of the verse simply discourages judging hypocritically. God never intended for His children to not judge. This passage, along with many others, simply points out the inexcusability of passing judgment upon matters where those judging are likewise guilty of the same actions. The point is not to avoid judgment altogether but to avoid hypocrisy while judging. This truth was taught during the Lord's ministry but also reiterated by the apostle Paul in Romans 2:1.
