“Discipleship” doesn’t always come with religious connotations:
“Schools, media, and peers are the ‘disciplers’ of America’s children–discipling them in secular humanism and vague, self-centered spirituality that has nothing to do with the gospel of Jesus Christ. It is no wonder then that, once teens are no longer under their parents’ direct authority, they drop their commitments like useless baggage.”
