48 The Jews then said, "That clinches it. We were right all along when we called you a Samaritan and said you were crazy - demon-possessed!" 49 Jesus said, "I'm not crazy. I simply honor my Father, while you dishonor me. 50 I am not trying to get anything for myself. God intends something gloriously grand here and is making the decisions that will bring it about.
51 I say this with absolute confidence. If you practice what I'm telling you, you'll never have to look death in the face." 52 At this point the Jews said, "Now we know you're crazy. Abraham died. The prophets died. And you show up saying, 'If you practice what I'm telling you, you'll never have to face death, not even a taste.' 53 Are you greater than Abraham, who died? And the prophets died! Who do you think you are!"
Matthew Henry's Commentary on John 8:48-53
Commentary on John 8:48-53
(Read John 8:48-53)
Observe Christ's disregard of the applause of men. those who are dead to the praises of men can bear their contempt. God will seek the honour of all who do not seek their own. In these verses we have the doctrine of the everlasting happiness of believers. We have the character of a believer; he is one that keeps the sayings of the Lord Jesus. And the privilege of a believer; he shall by no means see death for ever. Though now they cannot avoid seeing death, and tasting it also, yet they shall shortly be where it will be no more forever, Exodus 14:13.
