A Verse By Verse Commentary of the book of Psalms.
God says: "Praise is the strongest power in the universe. You have no idea how I bless the world when you praise Me. It’s not that your words or your songs in themselves carry any magical or mystical energy. It’s that when I hear the sweetness of your hearts attuned to Me, it sends a glorious fragrance into heaven. And whenever I smell that scent it fills me with energy and interest in blessing My pet project, earth." ~God
