I end, then, with this searching question. It is the most profound question a man can ever face in this life and world. Is there anything special about you? I am not asking whether you are living a good, moral, upright life. I am not asking whether you say your prayers, or whether you go to church regularly. I am asking none of these things. There are people who do all that and still are not Christians. If that is all, what do ye more than others, what is there special about you? Is there anything of this special quality about you? Is there something of your Father about you? It is a fact that children sometimes do not resemble their parents very closely. People look at them and say: "Yes, there is something of his father there after all," or "I see something of the mother; not very much, but there is something." Is there just that much of God about you? That is the test. If God is your Father, somewhere or another, in some form or other, the family likeness will be there, the traces of your Parentage will inevitably appear. What is there special about you? God grant that as we examine ourselves we may discover something of the uniqueness and the separateness that not only divides us from others, but which proclaims that we are children of our Father which is in heaven.
