The Holy Spirit is God. The person who indwells us, leads us, and purifies us is no one less than God, the Holy Spirit. The simple evidence for this is the frequent designation “Spirit of God.” The Spirit is “of God” not because God created him, but because he shares God’s nature and comes forth eternally from God (see 1 Corinthians 2:10–12).
If the Son of God is equally eternal with the Father, as John 1:1–3 makes clear that he is, then so is the Holy Spirit equally eternal with them both, because, according to Romans 8:9–11, the Spirit of Christ is one and the same with the Spirit of God. If this were not so, we would have to imagine that there was a time when the Son had no Spirit and the Father had no Spirit. But the Holy Spirit is essential to the relationship between the Father and the Son. He is, to use Handley C.G. Moule’s words, “the Result, the Bond, the Vehicle, of their everlasting mutual delight and love” (Person and Work of the Holy Spirit, p. 28).
As far back into eternity as God the Father has loved the Son, there has been an infinite Holy Spirit of love and delight between them, who is himself a divine Person. Therefore, as Jesus prays for the church in John 17:26, he asks his Father for nothing less than the Holy Spirit when he says, “I made known to them your name, and I will continue to make it known, that the love with which you have loved me may be in them, and I in them.
The most glorious of all truths that we will discover in these 7 devotionals is that when the Holy Spirit comes into our lives, he comes not merely as the Spirit of the Son, nor merely as the Spirit of the Father, but as the Spirit of infinite love between the Father and the Son, so that we may love the Father with the very love of the Son, and love the Son with the very love of the Father.
