I think God uses Teenagers to have our faith grow through him, to get really for children so they can preach the word to their children, i also think God uses Teenagers to grow stronger in him and to get used to go to church and read the Bible God uses us at a young age like now or younger so when we grow up to get a job, we can possibly become a Preacher, Minister, or a Pastor God got plans for us and it kind of like when David went against Goliath, David was 16 years old and God was with him when he went against Goliath.
