Even God’s law, which we often regard as a stern taskmaster, is a delight to the redeemed heart (Pss. 1:2; 119:97; Rom. 7:22), a gift of God’s grace (Ps. 119:29). It is our way of life, not in the sense that it brings us eternal life apart from grace, but in the sense that it brings fullness of blessing to those who are saved by grace and walk in God’s ways (Lev. 18:5; Deut. 5:33; 8:3; 11:13-15; 28:1-4; 30:11-20). God has given the law for our good (Deut. 10:12-13; 4:40; 12:28).
