In the midst of mayhem, God will, inevitably, be made known to us in a myriad of ways. Plan devotional time before every rehearsal, whether that is by yourself or with others. Think of every rehearsal as a potential time of spiritual formation. Be fastidious about timely preparation. Right before a service or concert begins, there are usually many things to think of, worry about or check on.
Energy can be a bit frantic.
Close your eyes. You have time. Call on the Holy Spirit. Yours is a share in the work of the Lord's Spirit who opens our hearts to God's holy word. Yours is a share in the work of the Lord's Spirit who draws us together into one, who makes harmony out of discord, who sings in our hearts the lyric of all that is holy.
