12 There is a way that seems right to a man, but its end is the way of death. 13 Even in laughter the heart may sorrow, and the end of mirth may be grief. (Proverbs 14:12–13, NKJV)
The futility of trusting one’s feelings as a reliable guide for knowing right from wrong and truth from error is witnessed by the facade that emotions often display. Laughter may in fact hide sorrow, so that while one expresses mirth outwardly, grief exists within. This teaches us not to rely on what feels right, for they can mislead us even as they can mislead others. In contrast to “letting your conscience be your guide,” Scripture says, “Your word is a lamp to my feet and a light to my path” (Psa. 119:105). Divine truth, not human emotions, determine the way that pleases God. We must “buy the truth, and do not sell it, also wisdom and instruction and understanding” by going to the word of God to know and practice the will of God (Prov. 23:23; Jas. 1:25).
