John Calvin on John 7:30

30. Therefore they sought to seize him. They had no want of will to do him mischief; they even made the attempt, and they had strength to do it. Why, then, amidst so much ardor, are they benumbed, as if they had their hands and feet bound? The Evangelist replies, because Christ’s hour was not yet come; by which he means that, against all their violence and furious attacks, Christ was guarded by the protection of God. And at the same time he meets the offense of the cross; for we have no reason to be alarmed when we learn that Christ was dragged to death, not through the caprice of men, but because he was destined for such a sacrifice by the decree of the Father. And hence we ought to infer a general doctrine; for though we live from day to day, still the time of every man’s death has been fixed by God. It is difficult to believe that, while we are subject to so many accidents, exposed to so many open and concealed attacks both from men and beasts, and liable to so many diseases, we are safe from all risk until God is pleased to call us away. But we ought to struggle against our own distrust; and we ought to attend first to the doctrine itself which is here taught, and next, to the object at which it aims, and the exhortation which is drawn from it, namely, that each of us, casting all his cares on God, (Psalm 55:22; 1 Peter 5:7,) should follow his own calling, and not be led away from the performance of his duty by any fears. Yet let no man go beyond his own bounds; for confidence in the providence of God must not go farther than God himself commands.

John 7:31-36

31. And many of the multitude believed in him, and said, When Christ shall come, will he do more miracles than this man doth? 32. The Pharisees heard the multitude muttering these things concerning him; and the Pharisees and priests sent officers to seize him. 33. Jesus, therefore, said to them, Yet a little while am I with you, and I go to him who hath sent me. 34. You shall seek me, and shall not find me; and where I am, you cannot come. 35. The Jews, therefore, said among themselves, Whither will he go, that we shall not find him? Will he go to those who are scattered among the Greeks, “Vers ceux qui sont espars entre les Grecs.” and teach the Greeks? 36. What is this saying which he hath spoken, You shall seek me, and shall not find me, and whither I go, you cannot come?
