If I know anything I know camp. If you do youth camp, can I encourage you to start praying now. Here's a few prompts to get you going.
The Campers
Pray for the kids who are going, should go and can't go.
The Camp Speaker
Pray that the speaker speaks truth and doesn't outshine Jesus.
The Parents
Pray for homes to receive these changed kids and through them, change their homes.
The Follow Up
The last altar call is not the end. The end of camp is not the end. Pray to carry the ball over the finish line by following up with those who made commitments to Christ during camp.
Above all things, pray for God's grace in all things.
