In Isaiah 9:6, the child prophesied to be born will be called “Everlasting Father.”
For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Isa 9:6 NIV
At first look, the text seems to be calling Jesus, the second person of the Triune Godhead, the Father. However, there is no need for confusion or a perceived contradiction. John Gill explains:
The everlasting Father; which does not design any relation of Christ in the Godhead; and there is but one Father in the Godhead, and that is the first Person; indeed Christ and the Father are one, and the Father is in him, and he is in the Father, and he that has seen the one has seen the other, and yet they are distinct, Christ is not the Father; the Son and Spirit may be considered with the first Person as Father, in creation and regeneration, they being jointly concerned therein, but not in the Trinity: it is easy to make it appear Christ is not the Father, but is distinct from him, since he is said to be with the Father from eternity, to be the Son of the Father in truth and love, his own Son, his only begotten and beloved Son; Christ frequently calls the first Person his Father, prayed to him as such, and is our advocate with him, as well as the way unto him; he is said to be sent by the Father, to come from him, and to go to him; and many things are said of Christ that cannot be said of the Father, as his being made flesh, suffering and dying in the room of his people; and the Father is said to do many things unto him, as to anoint him, to seal him, to show him all he did, to commit all judgment to him, and give him to have life in himself as he had: but Christ is a Father with respect to chosen men, who were given him as his children and offspring in covenant; who are adopted into that family that is named of him, and who are regenerated by his Spirit and grace: and to these he is an “everlasting Father”; he was so from everlasting; for regeneration and faith do not make men children, but make them appear to be so; God’s elect are children previous to the Spirit’s work upon them, and even to the incarnation and death of Christ; adoption is an act of the will of God in covenant from eternity: and Christ is a Father to these unto everlasting; he will never die, and they shall never be left fatherless; he and they will ever continue in this relation; he as such supplies them with everlasting provisions, he clothes them with everlasting raiment, he gives them an everlasting portion, promotes them to everlasting honour, saves them with an everlasting salvation, bearing an everlasting love to them. Some render the words, “the Father of eternity” (s); the author of eternal life, who has procured it for his people, and gives it to them; or to whom eternity belongs, who inhabits it, and is possessed of it, is the everlasting I AM, was before all persons and things, was set up in an office capacity from everlasting, and had a glory with the Father before the world was, in whom eternal election, and with whom the everlasting covenant, were made. The Septuagint version is, “the Father of the world to come” (t); of the Gospel dispensation; so called, Hebrews 2:5 the legal dispensation, when in being, was the then present world, at the end of which Christ came; this is now at an end, and a new state of things has taken place, which with respect to the Old Testament saints was the world to come, and of this Christ is the Father or author; as the law came by Moses, and he was the father of the legal dispensation, grace and truth are come by Christ, the Father and author of the Gospel dispensation; the doctrines of it are from him, and the ordinances of it by him; and he is the father of that state or world to come after the resurrection, the New Jerusalem church state, and also of the ultimate glory.
