Think about your school for a moment. This is often called Christ's Great Commission, His command to give everyone the opportunity to say yes to His love and forgiveness. Your school is an important part of the world Jesus was talking about. It is within these smaller groups that influence, good or bad, is the greatest. List all the groups you can identify at your campus.
Good news travels the fastest among friends.
Prayer will make a big difference at your school. List their names and how you will pray for them. Prayers not prayed are prayers unanswered. Training is keeping sharp. Your confidence to lead and make a difference is going to come from God Himself, through His Holy Spirit.
