Your children will go to public school and they will be trained for somewhere around 15,000 hours in ungodly secular thought. And then they'll go to Sunday school and they'll color a picture of Noah's ark. And you think that's going to stand against the lies that they are being told?
Men, your primary responsibility in your home, after your wife, is you to disciple your own children. And if you don't do it, you're in sin; you are in sin. And if you turn it over to a Sunday school teacher, you are in sin. And you are to be teaching these children more than just stories about animals that went into Noah's ark. You're to be teaching them about God, about radical depravity, about blood atonement, about propitiation, expiation, justification, sanctification; you are to teach your children!
Teach the Scriptures to your children daily, discipline your children consistently, and love your children unconditionally. If you do these things, you will have acted biblically.
I would not send my child to a vacation Bible school in 99.9% of the Baptist churches in America. Have some teacher that doesn't even understand anything about the gospel of Jesus Christ, ask those little children, 'How many of you want to go to Heaven?' and damn most of them! Harden their heart to the gospel with some silly profession of faith because it was a silly proclamation of the gospel! It brought no genuine repentance, it brought no faith; it's no different than the Roman church that baptizes every infant that is born.
