Proverbs 22:6 tells us
Train up a child in the way he should go, even when he is old he will not depart from it.
The responsibility of a parent is to train a child... not just raise a child. People can raise dogs, cows, chickens, or any other kind of animal they like. Scripture tells us that we should train our children. We have a responsibility that is greater than just providing food and shelter and raising them. If anyone is interested I highly recommend Reb Bradley's Child Training Tips book.
The work of our heavenly Father (through the Messiah) is to author and perfect our faith (Hebrews 12:2) and conform us into the image of His Son (Romans 8:29). We as parents should actively assist in this effort rather than oppose it through laziness or passivity. Unfortunately, I find examples of such opposition to be far too common in the world.
