We need the Holy Spirit because the Spirit makes Christ’s love real (Ephesians 3:16-19). And to Paul that was a burning passion, that we understand Christ’s love for us so well that we’ll trust our lives to Christ like a woman trusts her life to a man in marriage (2 Corinthians 11:2).
Paul knew what the Holy Spirit would then do in people who could love and trust Jesus like that. The Spirit would “transform (them) into Christ’s likeness with ever-increasing glory,” 2 Corinthians 3:18. Just as the workings inside the body of a young, gangly girl transform her into a poised and beautiful woman, so does the Holy Spirit work inside us to grow us up into the beauty and likeness of Christ in everything (Ephesians 4:13-15).
We can “live a life of love, just as Christ loved us,” Ephesians 5:1. Imagine being a person like that – where nothing but “what is helpful for building others up according to their needs” is what we think about and say to people, Ephesians 4:29. But this is where the Holy Spirit comes in. I can’t make myself into such a person, but the Spirit can, and wants to.
How I must “grieve the Holy Spirit,” verse 30– or break the Spirit’s heart – when I forget I have the HOLY GOD living and breathing his life in me all the time. God has made himself as intimate to me as he can, by actually “sealing” himself inside me (verse 30). He’s willingly stuck himself inside me for life, with no escape. He has no intention of escaping either, because now that he’s in me he can do what it takes to repair all the damage, suture up the wounds, do a heart transplant and pump his life into my bloodstream. And I’ve got that now working inside me, simply for believing Christ really does love me and I trust him.
That was all it took for the door to my spirit to open up to the Holy Spirit. “Believe in the good news of the kingdom of God and the name of Jesus Christ,” Acts 8:12, and because of that belief the Holy Spirit “comes upon us,” verse 16-17. Now the power begins – transformation, healing, and growing us up into an entirely new creation from the inside out, unrecognizable from the “infants” we used to be “blown here and there by every wind of doctrine and the cunning and craftiness of men in their deceitful scheming,” Ephesians 4:14.
No more are we the easily influenced youngsters we were. We’re being grown up to become wise, strong and beautiful, fit to be the wife of Christ himself (2 Corinthians 11:2). And it’s the Holy Spirit’s great pleasure to do that for everyone.
