If you truly love your children, don’t fill their heads with myths and threats of eternal punishment (HELL). Telling your child that after he dies, he shall go to hell, is wrong. It is a threat that lingers in his mind, forming images of fire and eternal suffering of unimaginable proportions.
Instead, teach them The Golden Rule, the power of reason and the benefits of applying a healthy skepticism towards life. Teach them how to think, not what to think. If they decide to embrace a religion once they attain adulthood, that will be their choice and not yours.
If more parents started adopting this approach, we would have better adjusted kids and a better adjusted world.
