“Thus saith YHWH, thy Redeemer, the Holy One of Israel; I am YHWH your God which teaches you to profit, which leads you by the way that you should go. O that you had hearkened to my commandments! then had your peace been as a river, and your righteousness as the waves of the sea.”
Obedience to YHWH, our God, brings peace and righteousness into our lives. The Creator who made us, knows exactly how we best function. All it takes on our part is some humility to live by His instructions, and not live in the pride of supposedly knowing better.
