The Psalms lay out all of life. They walk us through the ups and the downs. When I read Psalm 96, it is the ups of life that I see most clearly. The psalmist calls out for all of creation to praise the Lord. He does this on the basis of good theology. The Lord made heaven and earth. He is the true God. Therefore he is the only one that deserves our worship. It is this theology that causes him to sing a song of praise to the Lord.
