Here is a mystery indeed. That scene in Eden is also a parable. It was not good for Christ to be alone. He needed one to love and to give love. But there was none among unfallen angels that could answer to Him. And therefore God the Father sought a bride for his Son from among the children of men; yea, He took the Second Eve from the wounded side of the Second Man, as He lay asleep in the garden-grave.
Redeemed men compose that bride. The Saviour loves them, as a true man who for the first time loves a pure and noble woman. He does not love them because they are fair, but to make them so. He has approved his love by becoming man, and giving Himself to death. By his blood, and Word, and Spirit, He is sanctifying and purifying them for Himself. The process is long and severe; but He nourishes and cherishes them, as a man does his wounded flesh. And ere long, when the bride is complete in numbers and in beauty, the mystery that now veils her shall be flung aside, and amid the joy of creation, He will present her to Himself, without spot or wrinkle or any such thing; bearing his name, sharing his rank, and position, and wealth, and power, and glory, for ever and ever.
Then the Church shall cleave to Him for ever, and He shall cleave to her. And they twain shall be one spirit. And his own prayer shall be realized, offered on the eve of his agony and passion, "The glory which Thou hast given Me, I have given unto them; that they may be one, even as We are one."
