If once the human mind has arrived at the conviction that everything must be accounted for, or, as it is sometimes expressed, that there is uniformity, that there is care and order in everything, and that an unbroken chain of cause and effect holds the whole universe together, then the idea of the miraculous arises, and we, weak human creatures, call what is not intelligible to us, what is not in accordance with law, what seems to break through the chain of cause and effect, a miracle. Every miracle, therefore, is of our own making, and of our own unmaking.

It is due to the psychological necessities of human nature, under the inspiring influence of religious enthusiasm, that so many of the true signs and wonders performed by the founders of religion have so often been exaggerated, and, in spite of the strongest protests of these founders themselves, degraded into mere jugglery. It is true that all this does not form an essential element of religion, as we now understand religion. Miracles are no longer used as arguments in support of the truth of religious doctrines. Miracles have often been called helps to faith, but they have so often proved stumbling-blocks to faith, and no one in our days would venture to say that the truth as taught by any religion must stand or fall by certain prodigious events which may or may not have happened, which may or may not have been rightly apprehended by the followers of Buddha, Christ, or Mohammed.

Our Lord's ascension will have to be understood as a sublime idea, materialised in the language of children. Is not a real fact that happened, in a world in which nothing can happen against the will of God, better than any miracle? Why should we try to know more than we can know, if only we firmly believe that Christ's immortal spirit ascended to the Father? That alone is true immortality, divine immortality; not the resuscitation of the frail mortal body, but the immortality of the immortal divine soul. It was this rising of the Spirit, and not of the body, without which, as St. Paul said, our faith would be vain. It is the Spirit that quickeneth, the flesh profiteth nothing.

It will be to many of the honest disciples of Christ a real day of Damascus, when the very name of miracle shall be struck out of the dictionary of Christian theology. The facts remain exactly as they are, but the Spirit of truth will give them a higher meaning. What is wanted for this is not less, but more, faith, for it requires more faith to believe in Christ without, than with, the help of miracles. Nothing has produced so much distress of mind, so much intellectual dishonesty, so much scepticism, so much unbelief, as the miraculous element forced into Christianity from the earliest days. Nothing has so much impeded missionary work as the attempt to persuade people first not to believe in their own miracles, and then to make a belief in other miracles a condition of their becoming Christians. It is easy to say 'You are not a Christian if you do not believe in Christian miracles.' I hope the time will come when we shall be told, 'You are not a Christian if you cannot believe in Christ without the help of miracles.'
