Hate it when that happens! I want to scribble it down lest I forget it as fast as it came along. In the Babel account, humanity is active: "let us, let us, let us" and afraid "lest we be dispersed." And thus at the heart of Babel is man's attempt to reach God, to do and to work, to storm heaven by our deeds. And the Lord rejects this utterly and scatters people. When Babel is reversed it is clear that it is not our doing, but His giving which accomplishes and delivers salvation.
And in the Gospel today, when our Lord says: "the ruler of this world is coming. He has no claim on me, but I do as the Father has commanded me." The ruler of this world HAS a claim [note that the word claim is absent from the Greek; literally, he has nothing in me], has a piece of all who have sinned. As in Narnia, the traitors belong to the white witch. Jesus makes it clear that what's about to befall Him does not come about from Satan having a piece of him, for Satan can never get his clutches into Him. Rather, what our Lord "rises" to go meet is simply what His Father has commanded Him to do, and that's the measure of His love for the Father that He receives even what awaits on Calvary in obedience.
"Yeah, Father, yeah most willingly I'll do what Thou commandest" as we sing.
