Boys ages 9-14 (Grades 4-8) should join because it is our goal to help boys grow spiritually in all areas of life by providing Christian men to lead them using a uniquely designed structure, program, and materials.
Girls ages 9-14 (Grades 4-8) should join and come together and learn about God in Bible studies that are more applicable to them and doing crafts that are good for all ages. They also get to experience different leadership and structure.
Any young adult (21+ typically) should join; It is good to have conversations with those who are of similar age and intellect. It is nice to hear different points of view/input from everyone to further our knowledge.
