The call to "Rejoice" is a vibrant theme in the book of Philippians. One idea would be to select a song full of rejoicing to sing throughout your series.
You might choose the simple, child-like praise of “Rejoice in the Lord Always and Again I Say Rejoice,” or the classic “Rejoice the Lord Is King,” or the newer “Come People Of The Risen King,” (by Keith Getty, Kristyn Getty, Stuart Townend; ©2007 ThankYou Music), with its refrain “Rejoice, rejoice! Let every tongue rejoice! One heart, one voice, O Church of Christ, rejoice!”
