Why? Rejoice and praise; these are not strict duties or obligations for believers per se, but rather something that ought to spring naturally from ones spirit the deeper you enter into God’s embrace. So for all ye faithful, sing!
And we speak to our Creator:
My Divine and graceful Lord, I long to sing and praise Your name, and to show You that my heart belongs to Your Essence. In peace and joy I rejoice, for the closer I am to Your creation the bigger my heart grows, for You are our Rock, our Anchor, our Heavenly Father in salvation. Amen.
