Steve and Joe are best friends. They do everything together! Most of all, they like to meet at their hangout-the tree house! Steve believes in God, but Joe isn't so sure. How can Steve believe in someone he has never seen before? Steve does his best to help his friend see that God loves him and takes a personal interest in him, but sometimes it seems that Joe just isn't listening. One day, as they are exploring the woods nearby, they find a mysterious, old metal box hidden in an abandoned barn. Is this box somehow connected to Joe's questions about God? Joe has a hard time believing it all, but through a series of events and a cousin named Annabell, God works to show Joe just how much He cares. This is an excellent book to teach kids how to talk to their friends about God. It shows the power of friendship evangelism and the power of prayer. God wants to use us to share His love with others.
