Prayer is our way of communicating with God. It's a way to praise Him, ask for guidance, lift up our burdens, and rest in His promises. But, it's also a way to invite God into our midst. Matthew 18:20 says: "Where two or three gather in my name, there am I with them." This is the power of praying with others.
God calls us to "pray without ceasing" (1 Thessalonians 5:17), "seek His face always" (1 Chronicles 16:11), and "pray in the Spirit on all occasions with all kinds of prayers and requests" (Ephesians 6:18a).
Many choir directors open and/or close their rehearsals with a short prayer each week. This is an active way to invite God into the work we do and lift up specific joys and concerns shared by the group. Not only does this help focus the hearts and minds of those present on the meaning of what we do, I believe it also helps build community among choir members.
Coming together in prayer each week helps unite us and draw us closer to one another as we draw close to God.
