The moral law which reveals itself to conscience has seemed to certain authors so decisive a witness for God, that all other witnesses may be dispensed with. Kant, who exerted his great logical ability to prove that the speculative reason in searching after God inevitably loses itself in sophisms and self-contradictions, believed himself to have found in the practical reason or moral faculty an assurance for the Divine existence and government capable of defying the utmost efforts of scepticism. Sir William Hamilton has also affirmed that "the only valid arguments for the existence of God, and for the immortality of the human soul, rest on the ground of man's moral nature." Dr John Newman has insisted that conscience is the creative principle of religion, and has endeavoured to show how the whole doctrine of natural religion should be worked out from this central principle. A well-known living theologian of Germany, Dr Schenkel, has attempted to build up a complete theology on conscience as a basis, starting from the position that conscience is "the religious organ of the soul"--the faculty through which alone we have an immediate knowledge of God. These thinkers may have erred in relying thus exclusively on the moral argument--I believe that they have--but the error, if error there be, shows only the more clearly how convincing that argument has seemed to certain minds, and these assuredly not feeble minds. There is, besides, valuable truth underlying any exaggerations into which they may have fallen on the subject. There is probably no living practical belief in God which does not begin with the conscience. It is not reasoning on a first cause, nor even admiration of the wisdom displayed in the universe, which makes the thought of God habitually and efficaciously present to the mind. It is not any kind of thinking nor any kind of feeling excited by the physical universe or by the contemplation of society, which gives us an abiding and operative sense of God's presence, and of His relationship to us. It is only in and through an awakened and active conscience that we realise our nearness to God--His interest in us, and our interest in Him. Without a moral nature of our own, we could not recognise the moral character and moral government manifested by Him. We might tremble before His power, or we might admire His skill, but His righteousness would be hidden from us, His moral laws would be meaningless to us, and their sanctions would be merely a series of physical advantages or physical disasters. But a God without righteousness is no true God, and the worship which has no moral element in it is no true worship. As, then, it is only through the glass of conscience that the righteousness of God can be discerned, and as that attribute alone can call forth, in addition to the fear, wonder, and admiration evoked by power and intelligence, the love, the sense of spiritual weakness and want, and the adoring reverence,
