Love is communicative. This is a part of its very nature and essence. Its delight is to give, and especially to give itself; and all it wants or asks is a return. To love and to be beloved, to enjoy and to express that ardent and mutual affection by words and deeds,—this is love's delight, love's heaven. To love, and not be loved,—this is love's misery, love's hell. God is love. This is his very nature, an essential attribute of his glorious being; and as he, the infinite and eternal Jehovah, exists in a Trinity of distinct Persons, though undivided Unity of Essence, there is a mutual, ineffable love between Father, Son, and Holy Ghost. To this mutual, ineffable love of the three Persons in the sacred Godhead the Scripture abundantly testifies: "The Father loveth the Son;" "And hast loved them as thou hast loved me;" "This is my beloved Son in whom I am well pleased." And as the Father loves the Son, so does the Son love the Father: "But that the world may know that I love the Father," are his own blessed words. And that the Holy Ghost loves the Father and the Son is evident not only from his divine personality in the Godhead, but because he is essentially the very "Spirit of love" (Romans 15:30), and as such "sheds the love of God abroad in the heart" of the election of grace.
Thus man was not needed by the holy and ever-blessed Trinity as an object of divine love. Sufficient, eternally and amply sufficient, to all the bliss and blessedness, perfection and glory of Jehovah was and ever would have been the mutual love and intercommunion of the three Persons in the sacred Godhead. But love—the equal and undivided love of Father, Son, and Holy Spirit—flowed out beyond its original and essential being to man; and not merely to man as man, that is to human nature as the body prepared for the Son of God to assume, but to thousands and millions of the human race, who are all loved personally and individually with all the infinite love of God as much as if that love were fixed on only one, and he were loved as God loves his dear Son. "I have loved thee with an everlasting love," is spoken to each individual of the elect as much as to the whole Church, viewed as the mystical Bride and Spouse of the Lamb.
Thus the love of a Triune God is not only to the nature which in due time the Son of God should assume, the flesh and blood of the children, the seed of Abraham which he should take on him (Hebrews 2:14-16), and for this reason viewed by the Triune Jehovah with eyes of intense delight, but to that innumerable multitude of human beings who were to form the mystical body of Christ. Were Scripture less express, we might still believe that the nature which one of the sacred Trinity was to assume would be delighted in and loved by the holy Three-in-One. But we have the testimony of the Holy Ghost to the point, that puts it beyond all doubt or question. When, in the first creation of that nature the Holy Trinity said, "Let us make man in our image, after our likeness," and when, in pursuance of that divine council, "the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life, and man became a living, soul," God thereby uniting an immortal soul to an earthly body, this human nature was created not only in the moral image of God, but after the pattern of that body which was prepared for the Son of God by the Father.
