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.
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).
