101 I have restrained my feet from every evil way, that I may keep Your word. 102 I have not departed from Your judgments, for You Yourself have taught me. (Psalm 119:101–102, NKJV)
Self-discipline is essential in keeping the word of God. Discipleship requires discipline, both to order one’s life after the Master’s teachings and to refrain from conduct that is against the Master’s instruction (Lk. 6:40; Jno. 13:13-17). Pride is ever ready to puff up our confidence in ourselves. It deceptively assures us we could never deny our Lord (Matt. 26:35; cf. Prov. 16:18). Therefore, since “the spirit indeed is willing, but the flesh is weak,” we must continually “watch and pray, lest (we) enter into temptation” (Matt. 26:41). Utter commitment to God’s judgments (determinations) must governor our choices to refrain from evil and pursue good (1 Tim. 6:11; 2 Tim. 2:22; 1 Pet. 3:8-11). When we argue with God’s word to justify our sinful choices and conduct, we have allowed personal judgments to control us instead of the decisions of God. (That’s pride at work.) Jeremiah said, “O Lord, I know the way of man is not in himself; It is not in man who walks to direct his own steps” (Jer. 10:23). God does not delight in those whose evil (sin) is called good (Mal. 2:17). Self-disciplined faith in God helps us guard against reversing God’s judgments and calling good evil, and evil good (Isa. 5:20-21; Prov. 17:15). God is our teacher, and His word shows us what is evil and what is good. Walking in God’s word is how we “watch” and avoid entering into sin.
