Caleb and Sophie are your average kids - curious about their world, taught about the character and expectations of God, and wanting to be faithful in what they do.
In each of these books the concepts of faith, hope, love, and love for others is distilled down to simple forms and then introduced in ways a child will understand – conversation, prayer, actions, and thoughts.
Sophie and Caleb react in ways that you would expect in a child – with simple faith and the sort of fruit of the Spirit you expect in young children.
