Again, it is taught in the promise of Jesus, already quoted, "And I will pray the Father, and He shall give you another Comforter... the Spirit of Truth" (John xiv. 16, 17). Here the three Persons of the Godhead are clearly revealed. The Son prays; the Father answers; the Spirit comes. The Holy Spirit is "another Comforter," a second Comforter succeeding the first, who was Jesus, and both were given by the Father. Do you say, "I cannot understand it"? Neither do I. Who can understand it? God does not expect us to understand it. Nor would He have us puzzle our heads and trouble our hearts in attempting to understand it or harmonise it with our knowledge of arithmetic. Note this: it is only the _fact_ that is revealed; _how_ there can be three Persons in one Godhead is not revealed. The _how_ is a mystery, and is not a matter of faith at all; but the _fact_ is a matter of revelation, and therefore a matter of faith. I myself am a mysterious trinity of body, mind, and spirit. The fact I believe, but the _how_ is not a thing to believe. It is at this point that many puzzle and perplex themselves needlessly. In the ordinary affairs of life we grasp facts, and hold them fast, without puzzling ourselves over the _how_ of things. Who can explain _how_ food sustains life; how light reveals material objects, how sound conveys ideas to our minds? It is the fact we know and believe, but the _how_ we pass by as a mystery unrevealed. What God has revealed, we believe. We cannot understand _how_ Jesus turned water into wine; _how_ He multiplied a few loaves and fishes and fed thousands; _how_ He stilled the stormy sea; _how_ He opened blind eyes, healed lepers, and raised the dead by a word. But the facts we believe. Wireless telegraphic messages are sent over the vast wastes of ocean. That is a fact, and we believe it. But _how_ they go we do not know. That is not something to believe. It is a matter of pure speculation, and is unexplained. An old servant of God has pointed out that it is the fact of the Trinity, and not the _manner_ of it, which God has revealed, and made a subject for our faith. But while the Scriptures reveal to us the fact of the personality of the Holy Spirit, and it is a subject for our faith, to those in whom He dwells this fact may become a matter of sacred knowledge, of blessed experience.
