That's happening every day. The Christian plea goes unheard. The children are being lost. The world exists by chance. Man's fulfillment, to the atheist, is when he no longer needs the idea of God.
Life has no known purpose.
Sin is a delusion. Faith in God is openly derided in most science classes. To a child, God exists. His faith in God is permanently crippled or it dies with atheistic evolution. The very foundation of a Christian's faith is destroyed, and results in a devaluation of life, which makes abortion, suicide and euthanasia appear more acceptable.
