Much of what Jesus says seems counterintuitive. He tells us to turn the other cheek instead of striking back in violence. He tells us to walk an extra mile if compelled to walk the first. He tells us that it is better for Him to leave His earthly ministry than to stay. As St. Paul says, the wisdom of God is deep and rich and unsearchable.
How could it possibly be better for God among us to leave us? Perhaps only if God the Holy Spirit then comes to dwell among His people. We are not left without the presence of God within us and among us. Perhaps only if we can understand a shred of the divine plan for human redemption, seeing that, like a flower, each flower petal is slowly opening up toward the eternal sun. The first petal must give way so the innermost buds can be nourished. We see through the glass darkly now, but later…
Jesus unequivocally tells us the Holy Spirit is a ‘He’. “...I will send Him to you…He will convict the world…” The divinity of the Holy Spirit is given to us, if even somewhat opaquely, in these passages. But not only these. The early Church prayed and thought, and prayed and thought some more, before articulating what had God revealed for the sake of furthering the Kingdom and spreading joy far and wide.
We behold the great mystery of the inner life of God with wonder and awe. The Father, Son, and Holy Spirit are each at work in our redemption and deification. As the Spirit comes to convict the world of sin and righteousness and condemnation, He does so in perfect harmony with the Son who gives Himself and the Father who is glorified in the Son.
