John Calvin on Hebrews 12:3

3. For consider him, etc. He enforces his exhortation by comparing Christ with us; for if the Son of God, whom it behaves 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, in order that he might animate us by his own example; yea, it is thus that we gather courage, which would otherwise melt away, and turn as it were into despair.

Hebrews Chapter 12:4-8

4. Ye have not yet resisted unto blood, striving against sin.

4. Nondum ad sanguinem restitistis adversus peccatum certando.

5. And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:

5. Et obliti estic exhortationis quae vobis tanquam filiis loquitur, Fili mi, ne disciplinam Domini negligas, et ne deficias dum ab eo argueris:

6. For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.

6. Quem enim diligit Dominus castigat, flegallat omnem filium quem suscipit.

7. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?

7. Si disciplinam sustinetis, Deus tanquam filiis offeertur: quis enim est filius quem pater non castiget?

8. But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.

8. Quod si disciplinae expertes estis, cujus participes sunt omnes, spurii igitur estis, non filii.
