Use this worship idea for several weeks running as you won't have time to do it all in one evening. This is a wonderful time of worship, AND it will give each member an opportunity to share a small part of their testimony.
The week before you begin using this praise activity, explain to your group that you would like them to bring one of their favorite praise songs to group. Explain that they need to bring the music and enough copies of the words so that everyone can have them.
Ask 3 people to bring their song each week until everyone has had a chance (you may want to make up a calendar and remind people weekly of their date).
The night of your meeting, have each of the assigned members hand out their words, play their song, and explain why that song means so much to them. Encourage people to sing along if they know the song.
Be sure to finish in a word of prayer, thanking God for the beauty of music and how it moves us to worship Him as our Creator.
