The Bible is filled with singing! To sing the praises of God is what many of the Psalms are all about. Singing as a form of worship (all of these disciplines should be seen as worship) whether alone in your prayer closet or among your fellow disciples is a key discipline. On key, off key, whatever kind of joyful noise you can make, worship the Lord in singing! And don’t think singing is just praise, we can lament in song as well as we can praise, but in either case, rejoice always!
