Failure in Judæ a. The many signs have failed to convince. The author explains this by the prediction in Isaiah 53:1, the arm of the Lord being interpreted of Messiah. And the ultimate cause is also dealt with in Isaiah 6:9 ff. The rule of God's working is that there comes a time when those who will not obey lose the power of doing so. The situation is similar to that foretold in the story of Isaiah's call. It was the Word of God, now incarnate in Jesus Christ, that appeared to the prophet. But disbelief was not universal, though fear made men keep silence.

37 But though he had done so many miracles before them, yet they believed not on him:
38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
39 Therefore they could not believe, because that Esaias said again,
40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
41 These things said Esaias, when he saw his glory, and spake of him.
42 Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue:
43 For they loved the praise of men more than the praise of God.
