There are no qualifiers in Scripture concern the age at which one can start sharing their faith with their Nathanael. Children will need help, but they often have tremendous zeal. And teens don’t want to see their Nathanaels spend eternity away from God. So, age-appropriate curriculum is available.
Following the theme but using related Scripture passages, this material includes not only ice breakers/games, but comprehensive lessons which includes Q & A for each lesson plus Small Group material and a weekly assignment for the teens to do in regard to their Nathanael.
