Marriage has all kinds of purposes: it provides the environment in which children may be born and properly reared. It provides the context in which the sexual instincts can be exercised in a God-intended way. But first and foremost, Genesis teaches us, it provides a very special friendship. In marriage a man and a woman can become the best of friends, knowing each other to such a depth that only God knows them better! This, too, is a gift from the Creator.
