John Calvin on John 7:24

24. Judge not according to the appearance. Having concluded his defense, he likewise administers a reproof on this ground, that they are carried away by wicked dispositions, and do not form a judgment according to the fact and the matter in hand. Circumcision was properly held by them in reverence; and when it was performed on the Sabbath-day, they knew that the Law was not violated by it, because the works of God agree well with each other. Why do they not arrive at the same conclusion as to the work of Christ, but because their minds are preoccupied by a prejudice which they have formed against his person? Judgment, therefore, will never be right, unless it be regulated by the truth of the fact; for as soon as persons appear in public, they turn their eyes and senses on them, so that the truth immediately vanishes. While this admonition ought to be observed in all causes and affairs, it is peculiarly necessary when the question relates to the heavenly doctrine; for there is nothing to which we are more prone than to dislike that doctrine on account of the hatred or contempt of men.

John 7:25-30

25. Some of the inhabitants of Jerusalem therefore said, Is not this he whom they seek to kill? 26. And, lo, he speaketh boldly, and they say nothing to him. Do the rulers actually know that this is truly the Christ? 27. But we know whence this man is; but when Christ shall come, no man will know whence he is. 28. Jesus therefore exclaimed in the temple, teaching and saying, You both know me, and you know whence I am; and I did not come of myself, but he who sent me is true, whom you know not. 29. But I know him, for I am from him, and he hath sent me. 30. Therefore they sought to seize him; but no man laid hands on him, because his hour was not yet come.
