“Let all that I am praise the Lord; with my whole heart, I will praise his holy name” (Psalm 103:1 ESV)

This psalm of David begins with an introspective imperative that every detail of his life, both within and without, would live in a continuous state of worshiping God. Was there an area where David worshiped his own will or had found his desire focused on another? If so, he commanded himself to “let all that I am,” every part of my “heart,” be focused on praising the Lord.
Is there an area in your life today that isn’t in alignment with God’s will for you? If there is, then how can you truly worship the Lord? How can you bring only part of your heart, part of your life to Him in praise? This is half-worship, and God will not accept it. Stop being half-hearted in following Jesus. Confess your sins and “let all” that you are praise the Lord. Praise Him with your “whole heart.”
