God of Grace and Glory
In this psalm, David brings the people into worship of God by drawing out three fundamental ways God displays His grace to mankind: He is Savior, He is Sovereign, and He is Sustainer. Thus, the reflection of the psalmist is clear, in that God is deserving of our worship. As we think of these attributes of God today, the same truth rings through to us. God truly is all of these things and more, and therefore, our fundamental purpose in life is to bring Him praise.
