Make a joyful noise unto the LORD, all ye lands. Serve the LORD with gladness: come before his presence with singing. Psalm 100: 1-2
We need to remember that we are to serve the LORD with gladness, and even a song, and not be resentful of the things we do for HIM. From scrubbing toilets to serving little kids in VBS, we should do it all for HIS glory and to serve HIM.
