As far as "forcing" him to do something against his will...? Well, I force him to get up, make his bed, pick up his clothes, feed our animals, go to school, practice piano, and do his homework just about everyday, and that's against his will as well. So...again, I ask you...what's your point?
Again, I'll state my point: Would she have taken it if her parents hadn't forced Christianity upon her? Yes or no?
(1) Are you a parent?
(2) I agree that some children do respond only to the "wishes of their parents" and that their choice to become a Christian may not be entirely, sincerely their own. But again, at some point, ultimately it IS THEY who must choose for themselves...no one, not even parents, can know the true nature of a person's heart, and parents cannot "choose" salvation for their children. It must be of their own volition. We can lead them, but we can't make them "drink the water."
