"But Jesus called them unto Him, and said, Suffer little children to come unto me, and forbid them not: for of such is the kingdom of God" (Luke 18:16).
A widely read book several decades ago, based its title, Suffer Little Children, on this plea of Christ, but used the words instead to refer to the terrible harm being suffered by America's little children in its public schools and humanistic social institutions. Not only were they being indoctrinated with evolutionary just-so-stories, but also with socialistic understanding of the world and its nations and people.
And if things were bad thirty and forty years ago, they are much worse today with the modern promotion of deviant lifestyles and wide use of behavior-modifying "medicines" to control behavior. There are certainly many good Christian teachers and schools, but the over-all trend is so bad that many Bible-believing churches and organizations are diligently promoting Christian schools and home schools as a needed means of escape from the deadly influence of public schools on the children.
Worst of all is the deliberate banning of prayer, God, the Bible, and Christ from the schools in a misused devotion to the myth of church/state separation. Instead of "suffering the little children" to come to Christ like He said, most of them do all they can to prevent it.
Those who promote this situation are in grave danger themselves. Jesus warned: "But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea" (Matthew 18:6).
There is a better way, of course. A good school, acting en loco parentis, should seek heartily to "bring them up in the nurture and admonition of the Lord" (Ephesians 6:4). HMM
