The challenge before us then is not merely to do what God says because He is God, but to desire what God says because He is good. The challenge is not merely to pursue righteousness, but to prefer righteousness. The challenge is to get up in the morning and prayerfully meditate on the Scriptures until we experience joy and peace in believing “the precious and very great promises” of God (Rom. 15:13; 2 Peter 1:4). With this joy set before us the commandments of God will not be burdensome (1 John 5:3) and the compensation of sin will appear too brief and too shallow to lure us.
