CEF - Ten More Talks for Teens, Youth Challenge by David Crutchley and published by Child Evangelism Fellowship.
Ten Talks for Teens is a manual of ten talks primarily for the eleven to fifteen year old age group. They are also suitable for an older age group with some adaptation. The lengths of the talks vary but are generally for around twelve to fifteen minutes. Some of the longer talks can be split into two. The manual is designed for use as a course or as self-contained lessons for one-off meetings. If using as a course you may decide the order of teaching. Some lessons are solely evangelistic; while others are for the young believer.
