What should (at first, then realizingvitvis what we must do!) We should/must Sing praises to God, sing praises: sing praises unto our King, sing praises.
Why? For God is the King of all the earth (To be precise: THE KING of all kings) and we should likewise sing praises with understanding (Why do we worship and sing? What have you recieved? Didn’t you wake up this morning?)
Our God reigneth over the heathen: God sitteth upon The throne of His holiness. The princes of the people are gathered together, even the people of THE God of Abraham: for the shields of the Earth belong unto God: He is To be greatly exalted In ALL our ways. Psalm 47:6-9
