“That God, though, worships human beings, it's enough to frighten hearers out of their wits, because people are not in the habit of saying that God worships human beings — in that special sense —but that human beings worship God.”

Context: So there you are; listen; as I said, God "worships" us in the sense of tending our worth. That we worship God, of course, doesn't need proving to you. It's on everybody's lips, after all, that human beings worship God. That God, though, worships human beings, it's enough to frighten hearers out of their wits, because people are not in the habit of saying that God worships human beings — in that special sense —but that human beings worship God.
So I've got to prove to you that God too does "worship" human beings, or you will consider, perhaps, that I have used the word very carelessly, and begin arguing against me in your thoughts, and finding fault with me because you don't in fact grasp what I have been saying. So it's agreed that this is what has to be demonstrated to you: that God also "worships" us; but in the sense I have already mentioned, that he tends our worth as his field, to make improvements in us. The Lord says in the gospel: I am the vine, you are the branches; my Father is the farm worker (Jn 15:5,1). What does a farm worker do? I'm asking you, those of you who are farm workers and farmers. What does a farm worker do? I presume he works his farm, that is, tends its worth, that is, "worships" it, in a sense. So if God the Father is a farmer or farm worker, it means he has a farm, and he works or "worships" his farm, and expects a crop from it.
