'Gladness' sets the tone for all of life with God — this is not reluctant, duty-bound religion. Serving God is meant to be joyful. And we come before God with singing — with our voices lifted in worship. Presence here means nearness to God; we draw near to Him through praise.
Memory phrase: Serve God with a glad heart and singing.
Talk about it: What is the difference between doing something because you have to and doing it because you want to and love it?
Prayer: God, I don't want to follow You because I have to — I want to follow You because I love You and it makes me glad. Help my heart stay joyful.
