At the very beginning of Jesus work in public, he is baptised and John the baptiser notes that he is the one who israel was waiting for.

John 1

29The next day he saw Jesus coming toward him and declared, “Here is the Lamb of God who takes away the sin of the world! 30This is he of whom I said, ‘After me comes a man who ranks ahead of me because he was before me.’ 31I myself did not know him; but I came baptizing with water for this reason, that he might be revealed to Israel.” 32And John testified, “I saw the Spirit descending from heaven like a dove, and it remained on him. 33I myself did not know him, but the one who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain is the one who baptizes with the Holy Spirit.’ 34And I myself have seen and have testified that this is the Son of God.”

Now the teachingof all the prophets –from Moses to Zechariah — was and is that G_d is one. The idea of the incarnation is offensive, blasphemous. And yet, at this time, the Holy Spirit descents, and Jesus is proclaimed God’s son — and the last of the prophets states it.

We cannot understand G_d nor the manner of G_d. What we know, we know in part. And at times, the smallness of our theology traps us into limiting or denying the works of G_d.
