Charles H. Spurgeon on Psalms 18:22

An unsound soul will not take notice of such a precept as opposeth his special sin; such a precept must go for a blank, which the soul throws by, and will not think of, but as conscience now and then puts him in mind of it, whether he will or no. But it is not so with a man in whom sincerity is; that precept which doth most oppose that sin to which he is most inclined, he labours to obey as well as any other. An unsound soul sets so many of God's statutes before him, as rules to walk by, as suits with himself and the times, and no more. Such precepts as oppose his special corruptions, or displease the times, and so expose him to suffering, these he baulks and puts away, as David here saith, and calls them as the rotten Scribes and Pharisees were wont to do, "least commandments," small things not to be regarded; which rottenness Christ took up roundly in those ironical words, "Whosoever shall break one of these least commandments, shall be called the least in the kingdom of God." Godly sincerity makes no difference of greatest and least between the precepts of God, but sets all before a man as a rule to walk by, and makes the soul laborious to observe all. "Then shall I not be ashamed when I have respect unto all thy commandments." Psalm 119:6. —Nicholas Lockyer, 1649.
