Ppl can argue until they are blue in the face, but that will never convince anyone that God exist. Christ says, no man comes to me unless the father draws him, so tell you kids you'll pray for them that the God of heaven will chose them to go to heaven. At best all you can do is pray for them. If you are saved, then they your entire family is sanctified. Once they leave the roost, they loose that sanctification and then they will notice a difference in their life, and may be ready for conversation. But the bible does say, "bring them up in the way they should go."
