There is not much that is more important for the Christian than his or her impact on the children. Like society in general, Christianity's future depends on children of today. The child of today becomes the adult of tomorrow.
But how the children turn out has a lot to do with what we do with them now. The negative impact on children is one reason I detest divorce so much, or perhaps I should say, why I detest insecure homes so much.
God expects parents to take care of the children, and he expects mamas and daddys to love each other. That is about as simple as it can be said.
When either of those expectations are not met, problems compound and it is usually the children who suffer most. Children have the right to expect a strong, secure, loving home; Spouses have the same right. Yet, it is not that way so many times. Worse, much of it happens in what should be Christian homes.
There are two passages in the Bible (there are many more) that speak to Jesus' view of children and their importance. Three gospels refer to a time in Jesus' busy ministry when people were bringing children to be touched by him. While Jesus' own disciples thought children were unimportant at the time and tried to keep the children away, Jesus said, "Let the children come to me, and do not hinder them, for the kingdom of God belongs to such as these."
His main point came in the next statement: "Anyone who will not receive the kingdom of God like a little child will never enter it." (See the Luke account, 18:15-17.) But here is the bigger one from Jesus. Jesus said (Mark 9:42), "And if anyone causes one of these little ones (I am assuming he's talking of children) who believe in me to sin, it would be better for him to be thrown into the sea with a large millstone tied around his neck."
While Jesus was likely talking about the judgment for those who do harm to the little ones, I also think what he says is true for the future in this life if we fail the children, because tomorrow's leadership is in today's kids.
