Now, it seems to me that such a figure as that is worth tons of theological lectures about the true nature of faith, and that it tells us, by means of a picture that says a great deal more than many a treatise, that faith is something very different from a cold-blooded act of believing in the truth of certain propositions; that it is the flight of the soul--knowing itself to be in peril, and naked, and unarmed--into the strong Fortress. What is it that keeps a man safe when he thus has around him the walls of some citadel? Is it himself, is it the act by which he took refuge, or is it the battlements behind which he crouches? So in faith--which is more than a process of a man's understanding, and is not merely the saying, 'Yes, I believe all that is in the Bible is true; at any rate, it is not for me to contradict it,' but is the running of the man, when he knows himself to be in danger, into the very arms of God--it is not the running that makes him safe, but it is the arms to which he runs. If we would only lay to heart that the very essence of religion lies in this 'flight of the lonely soul to the only God,' we should understand better than we do what He asks from us in order that He may defend us, and how blessed and certain His defence is. So let us clear our minds from the thought that anything is worth calling trust which is not thus taking refuge in God Himself. Now, I need not remind you, I suppose, that all this is just as true about us as it was about David, and that the emotion or the act of his will and heart which he expresses in these words of my text is neither more nor less than the Christian act of faith. There is no difference except a difference of development; there is no difference between the road to God marked out in the Psalms, and the road to God laid down in the Gospels. The Psalmist who said, 'Trust ye in the Lord for ever,' and the Apostle who said, 'Believe on the Lord Jesus Christ, and thou shalt be saved,' were preaching identically the same doctrine. One of them could speak more fully than the other could of the Person on whom trust was to be rested, but the trust itself was the same, and the Person on whom it rested was the same, though His Name of old was Jehovah, and His Name to-day is 'Immanuel, God with us.' Nor need I do more than point out how the context of the words that I have ventured to detach from their surroundings is instructive: 'Let all those that put their trust in Thee rejoice because Thou defendest them.' The word for defending there continues the metaphor that lies in the word for 'trust,' for it means literally to cover over and so to protect. Thus, when a man runs to God for His refuge, God 'Covers his defenceless head With the shadow of His wings.'
