As we think about all the types of people we preach to on Sundays, don't forget the children. They may be the biggest group of unreached people in your church...and I guarantee when you get on their level, the adults will be tracking right there with you. Spurgeon once said:
...He is no preacher who does not care for the children. There should be at least a part of every sermon and service that will suit the little ones. It is an error which permits us to forget this.
~ Charles Spurgeon, Spiritual Parenting, 15.
