Psalm 89:1   I will sing of the Lord’s great love forever; with my mouth I will make your faithfulness known through all generations.

It doesn’t matter to God if you can’t carry a tune. Sing away…or at least make some noise. As long as it comes from a joyful heart, God doesn’t care.

Psalm 100:1-2   Make a joyful noise unto the Lord, all ye lands. Serve the Lord with gladness: come before his presence with singing.

1 Chronicles 28:9a   And you, my son Solomon, acknowledge the God of your father, and serve him with wholehearted devotion and with a willing mind, for the Lord searches every heart and understands every desire and every thought.
