2. Korinther 13:3

Since--The reason why he will not spare: Since ye challenge me to give a "proof" that Christ speaks in me. It would be better if ye would "prove your own selves" (Co2 13:5). This disproves the assertion of some that Scripture nowhere asserts the infallibility of its writers when writing it. which--"who" (Christ). is not weak--in relation to you, by me and in this very Epistle, in exercising upon you strong discipline. mighty in you--has given many proofs of His power in miracles, and even in punishing offenders (Co2 5:11, Co2 5:20-21). Ye have no need to put me to the proof in this, as long ago Christ has exhibited great proofs of His power by me among you (Co2 12:12) [GROTIUS]. It is therefore not me, but Christ, whom ye wrong: it is His patience that ye try in despising my admonitions, and derogating from my authority [CALVIN].

In this chapter the apostle threatens to be severe against obstinate sinners, and assigns the reason thereof (Co2 13:1-6); then he makes a suitable prayer to God on the behalf of the Corinthians, with the reasons inducing him thereto (Co2 13:7-10), and concludes his epistle with a valediction and a benediction (Co2 13:11-14).

13:3-4 Christ speaks through me: Paul represented Christ to the Corinthian congregation, and he would exercise God’s power in dealing with them. • Paul’s weakness was patterned on the humiliation of Christ, who was crucified in weakness (see 8:9). Paul’s judgment on the sinners would be tempered by the constraint of Christ’s love (5:14-21). • We, too, are weak: Paul’s humanity was frail, yet he could draw on Christ’s strength (12:10).
