Your Silence About Christ Is Dogma

He's addressing parenting, but there's also a wider application:

It is impossible not to teach children about God, because not to teach them is to teach them plenty. It teaches them that Jesus does not matter much, that Mom and Dad don't consider him nearly as important or exciting as new furniture, or weekends at the lake, or Dad's job, or all the other things that fill their conversation. Silence about Christ is dogma….

It is not true that teaching children about God has to make them close-minded and irrationally prejudiced. It might if the parents are insecure and have their own faith built on sand. But if parents see compelling reasons for being a Christian, they will impart these to their children as well. Nobody accuses a parent of prejudicing a child's cosmology because he tells the child the world is round, and the little stars at night are bigger than the earth, and the sun really stands still while the earth turns. Why? Because we know these things are so and can give evidence to a child eventually that will support this truth. And so it is with those who are persuaded for good reasons that the Christian faith is true.

And, fourth, it is simply unloving and cruel not to give a child what he needs most. Since we believe that only by following Christ in the obedience of faith can a child be saved for eternity, escape the torments of hell, and enjoy the delights of heaven, it is unloving and cruel not to teach him the way….

A second objection some parents may raise is: I don't know enough about the Bible and about doctrine to teach my children and to answer their hard questions. There are two reasons why this should not stop you. First, it is never too late to begin to study and grow in your grasp of Bible truth. You may be a better teacher than a veteran because you are learning it fresh yourself….

The second reason your sense of inadequacy should not stop you is that some tremendously valuable things can be taught when you don't know the answer to a child's hard question. I can think of two. You can teach your child humility. If you are secure enough in God to show your ignorance rather than bluff and be a hypocrite, your child learns the beauty of humility. Second, you can teach your child to take some initiative of his own in solving problems.
