But, in religion, this hidden activity is evoked by a direct appeal: it is unearthed; it is summoned to come forward on its own account. God demands of this secret and innermost vitality that it should no longer lie incased within the other capacities, but that it should throw off its sheltering covers, and should emerge into positive action, and should disclose its peculiar and native character. God, the Father, calls faith out of its dim background into the front of the scene. He does this under the pressure of invocations, which address their appeals through, and by means of, the secular and visible material, within and behind which He is ever at work. This had, indeed, always told of His invisible and eternal Godhead: but it did so indirectly, by requiring Him as its constant pre-supposition and base. Now, it is so used as to bring God into direct and positive evidence, by means of acts, which bring forward the energies of His immediate Fatherhood. All the growth of Eden had always testified to the existence and the name of God: but a new stage was reached when He was felt moving, in evening hours, amid the trees of the garden. And as the Father presses forward out of His silent background, so the secret sonship in man emerges out of its deep recesses in positive response, using its own secular faculties by which to carry itself forward into evidence and action. This definite and direct contact between the God Who is the hidden source of all life, and the faith which is the hidden spring of all human activity--this disclosure by the Father, met by this discovery by the son--this is Religion: and the history of Religion is the story of its slow and gradual advance in sanity and clearness, until it culminates in that special disclosure which we call Revelation; which, again, crowns itself in that Revelation of the Father through the Son, in which the disclosure of God to man and the discovery by man of God are made absolute in Him Who is one with the Father, knowing all that the Father does, making known all that the Father is.
