John Calvin Commentary Hebrews 12:3

"For consider him that hath endured such gainsaying of sinners against himself, that ye wax not weary, fainting in your souls." — Hebrews 12:3 (ASV)

For consider him, etc. He enforces his exhortation by comparing Christ with us; for if the Son of God, whom it is fitting for all to adore, willingly underwent such severe conflicts, who of us should dare to refuse to submit with him to the same? For this one thought alone ought to be sufficient to conquer all temptations: that is, when we know that we are companions or associates of the Son of God, and that he, who was so far above us, willingly came down to our condition, so that he might encourage us by his own example. Indeed, it is in this way that we gather courage, which would otherwise melt away, and turn as it were into despair.
