Read Psalm 119:1-16, 161-168. How should we keep God’s commandments, and what are the blessings that come from doing that?

 The Bible depicts a daily life of faith as a pilgrimage (“walk”) with God in His path of righteousness. The life of faith is maintained by walking “in the law of the Lord” (Ps. 119:1, NKJV) and by walking “in the light of Your countenance” (Ps. 89:15, NKJV). These are by no means two different walks. Walking in the light of God’s countenance implies upholding God’s law. Equally, walking “in the law of the Lord” involves seeking God with the whole heart (Ps. 119:1, 2, 10).

 Being “undefiled in the way” is another way the Psalms describe the righteous life (Ps. 119:1). “Undefiled” describes a sacrifice “without blemish” that is acceptable to God (Exod. 12:5). Likewise, the life of the righteous individual is a living sacrifice (Rom. 12:1). Thus, a love for sin must not defile it. A life devoted to God is also a “perfect way,” meaning that the person assumes a right direction in life that is pleasing to God (Ps. 101:2, 6; see also Ps. 18:32).

 Keeping God’s commandments has nothing to do with a legalistic observance of divine rules. On the contrary, it consists of “a good understanding” of the difference between right and wrong and good and evil (Ps. 111:10; see also 1 Chron. 22:12), and involves the whole person, not merely outward actions. Being “undefiled,” keeping God’s commandments and seeking God with the whole heart, are inseparable attitudes in life (Ps. 119:1, 2).

 God’s commandments are a revelation of God’s will for the world. They instruct people on how to become wise and to live in freedom and peace (Ps. 119:7-11, 133). The psalmist delights in the law because the law assures him of God’s faithfulness (Ps. 119:77, 174).

 “Great peace have those who love Your law, and nothing causes them to stumble” (Ps. 119:165, NKJV). The image of stumbling depicts moral failure. As the lamp to the psalmist’s feet (Ps. 119:105), God’s Word protects us from temptations (Ps. 119:110).
