Verse 2. All the rest - Who have since then sinned in any of these kinds. I will not spare - I will severely punish them.
Verse 4. He was crucified through weakness - Through the impotence of human nature. We also are weak with him - We appear weak and despicable by partaking of the same sufferings for his sake. But we shall live with him - Being raised from the dead. By the power of God in you - By that divine energy which is now in every believer, 2 Cor. xiii, 5.
Verse 5. Prove yourselves - Whether ye are such as can, or such as cannot, bear the test - This is the proper meaning of the word which we translate, reprobates. Know ye not yourselves, that Jesus Christ is in you - All Christian believers know this, by the witness and by the fruit of his Spirit. Some translate the words, Jesus Christ is among you; that is, in the church of Corinth; and understand them of the miraculous gifts and the power of Christ which attended the censures of the apostle.
Verse 6. And I trust ye shall know - By proving yourselves, not by putting my authority to the proof.
Verse 7. I pray God that ye may do no evil - To give me occasion of showing my apostolical power. I do not desire to appear approved - By miraculously punishing you. But that ye may do that which is good, though we should be as reprobates - Having no occasion to give that proof of our apostleship.
Verse 8. For we can do nothing against the truth - Neither against that which is just and right, nor against those who walk according to the truth of the gospel.
Verse 9. For we rejoice when we are weak - When we appear so, having no occasion to show our apostolic power. And this we wish, even your perfection - In the faith that worketh by love.
Verse 11. Be perfect - Aspire to the highest degree of holiness. Be of good comfort - Filled with divine consolation. Be of one mind - Desire, labour, pray for it, to the utmost degree that is possible.
