Phil.2:5-8 is also a powerful testimony to the deity of Christ. Let us concentrate on vs.6, which says of Christ: “Who, being in the form of God, thought it not robbery to be equal with God”. Christ was “in the form of God.” This means he was fully God – just as when, in vs.7, it says he “took upon him the form of a servant, and was made in the likeness of men”, it means he became fully man. And we are told he was equal with God. And yet – who is equal with God? No created being is equal with the uncreated God! “To whom then will ye liken me, or shall I be equal? saith the Holy One” (Isa.40:25). “To whom will ye liken me, and make me equal, and compare me, that we may be like?” (Isa.46:5). No created being can be equal with God. If, then, Christ was equal with God, he must be God. And so the Scriptures declare him to be.
Finally (not because there are no more, but because what has been given is ample testimony for now), there is Acts 20:28, where elders are told to “feed the church of God, which he hath purchased with his own blood.” We know that Christ purchased the church with his blood; that it was he who died on the cross, and shed his blood there, and not God the Father, nor the Holy Spirit. And thus, again, Christ is declared to be God.
All these portions of Scripture, as well as numerous others, reveal the glorious truth that, as certainly as the Father is God, so the Son is God; and yet, that there is only one God.
Nor, it must be firmly asserted, do the Scriptures teach that, since there is only one God, and since the Father is God, and the Son is God, the Father is the Son, and the Son is the Father. This is an absolutely false doctrine, and as much a denial of the Trinity as is the false doctrine that the Son is not God. The Father and the Son are distinct as persons. As Jn.1:1 says, “In the beginning was the Word, and the Word was with God [i.e. the Son was with God the Father], and the Word was God [i.e. the Son was God, as much as the Father was God; but the Son was not the Father].” They are distinct as persons; yet but one God. Let us go as far as Scripture, but no further. Let us adore the God who is revealed in his Word, but not attempt to delve into that which is not revealed.
Secondly, we must consider some portions of God's Word that reveal the Holy Spirit to be God, as well.
Matt.28:19 speaks of “the name of the Father, and of the Son, and of the Holy Ghost” – and therefore, since the Father is God, and the Son is God, it follows that the Holy Spirit is God. It cannot be otherwise; and indeed, this is how Scripture reveals him. And yet various cults deny that the Holy Spirit is God, claiming that he is no more than an impersonal force, a ‘wind,’ etc.
That the Holy Spirit is God, is revealed by the miraculous conception of Jesus in the womb of the virgin: “When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost” (Matt.1:18); “that which is conceived in her is of the Holy Ghost” (vs.20). The Lord Jesus was conceived in the womb of Mary by the power of the Holy Spirit. But now, take note of Lk.1:35: “And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.” Although Jesus was conceived in the womb of Mary by the Holy Spirit, he is never once called in Scripture the Son of the Holy Spirit, but always – the Son of God! God the Father was his Father. The Holy Spirit, then, is God!
In Acts 5:3,4, we have the account of Peter's words to Ananias. Peter said, “Ananias, why hath Satan filled thine heart to lie to the Holy Ghost…?…thou hast not lied unto men, but unto God.” Peter declared that to lie to the Holy Spirit, is to lie to God! The Holy Spirit, then, is God.
