It’s a three-fer. Three vital cornerstones of faith in one psalm. Say thank-you, behave yourself, and receive redemption. This scripture sheds light on the purpose of prayer. Beyond the personal fulfillment of offering thanksgiving, you’re offered an explanation of sorts as to why ancient sacrifice rituals have been exchanged for praise filled prayer. Next you’re reminded to live righteously. When you accomplish the first two, you are awarded the third. Salvation of God is yours.
