In verse 18 we learn that if we hearken to the commandments we’ll have peace like a river and our righteousness will be like the waves of the sea. Interesting analogies. “Peace as a river” conjures up images of wide, deep, calm waters. A river moves from place to place and is never stagnant. Rivers are what people live near. They provide transportation and are life sustaining (like the Nile). “Righteousness as the waves of the sea” refers to a different sort of body of water. Waves denote strength and relentlessness. Righteousness doesn’t usually have that reputation, but it surely deserves it, as righteousness born of hearkening to the Lord’s commandments wreaks havoc on the designs of the adversary. Living the commandments brings a deep abiding peace and an unconquerable righteousness which will bring us joy in this life and the promise of life eternal in the world to come. Let us then hearken to the Lord’s commandments, especially giving attention to the first and great commandment to love the Lord with all our heart, mind and strength. And remember the second, also – to love our neighbor (and spouse and family) as ourselves.
