Summer is the best time of the year for kids and youth to grow in their relationship with Christ. There are a lot of opportunities for young people to focus on that relationship. No school and breaks from many activities and athletics, allow more time for God. I remember that it was at summer camp that I felt God tell me to go to a Bible college and it was at a summer conference that I knew I was supposed to go into youth ministry.
It is amazing what we can hear from God when we give Him the time of day. He still speaks today. The problem is that we normally don't slow down to listen to what He is saying.
