Most parents don't want their precious little child to experience GUILT over wrong doing, i.e., sin; but without it there can be NO SALVATION! A child who isn't old enough to understand that they've sinned against God cannot be saved, for salvation is coming to Jesus Christ to be forgiven of sins. I do believe that a 5 or 6 year old can understand this truth, which is why I hate The Picture Bible, because it presents a bunch of cute Bible stories to children without showing them their personal sinfulness (as the Bible does). Christianity is NOT religion! Christianity is a personal relationship with Jesus Christ, which begins with us realizing that we are dirty, rotten, hell-deserving sinners in need of a Savior!
