I hope that you shall know He presses them still more urgently, while indulging this confident persuasion -- that he will not be rejected by the Corinthians. One of two things was necessary -- that they should either assign to Paul the honor due to an Apostle, or condemn themselves for unbelief, and acknowledge that they have no Church. He softens, however, the severity of the statement, by making use of the expression -- I hope; but in such a manner as to remind them the better of their duty; for to disappoint the hopes that have been entertained as to our integrity, is excessively cruel. "I hope," says he, "that you shall know -- when you have been restored to a sound mind." He prudently, however, says nothing as to himself in this second clause, calling them to consider God's benefits, by which they had been distinguished; nay more, he puts their salvation in the place of his authority.

But I trust - The sense of this verse is," Whatever may be the result of your examination of yourselves, I trust (Greek I hope) you will not find us false and to be rejected; that is, I trust you will find in me evidence that I am commissioned by the Lord Jesus to be his apostle." The idea is, that they would find when he was among them, that he was endowed with all the qualifications needful to confer a claim to the apostolic office.

Ye shall know that we are not reprobates - Ye have had, and ye shall have, the fullest proof that I have preached the true faith among you; and that God has confirmed it by his testimony; and thus that I am proved and manifested to be what I ought to be, and shown to be approved of God.

(3) But I trust that ye shall know that we are not reprobates.
(3) He appeases that sharpness, trusting that they will show themselves towards their faithful apostle, able and willing to be taught. And he also adds this, that he does not seek his own fame and estimation, so that they may serve their saviour, which is the only mark that he shoots at.

But I trust that ye shall know,.... Whether they were reprobates or not, the apostle would not pretend to say; that he left to themselves, and of which they were capable of making judgment for themselves: however, he hoped and believed, that he and his fellow apostles would give such proof of themselves, as that they should know certainly
that we, says he,
are not reprobates; men void of judgment in the doctrines of the Gospel, but have light, knowledge, and understanding in them; or useless and unprofitable in the ministry, but were the savour of life unto life to many; were ministers by whom others believed; were successful labourers in the Lord's vineyard, and builders in his house; and were made very useful for the conversion, comfort, and edification of many souls: or that they were not men disapproved either by God, or his people; since as they faithfully served Christ in the ministration of the Gospel, they were acceptable to God, and approved of men: or were not men without a proof of Christ speaking in them; they might assure themselves they would have too soon, for some of them, an evidence of that power and authority which Christ had lodged in them, to punish such as repented not of their evils.

we . . . not reprobates--not unable to abide the proof to which ye put us (2-Corinthians 13:6). "I trust that" your own Christianity will be recognized by you (observe, "ye shall know," answers to "know your own selves," 2-Corinthians 13:5) as sufficient "proof" that ye are not reprobates, but that "Christ speaks in me," without needing a proof from me more trying to yourselves. If ye doubt my apostleship, ye must doubt your own Christianity, for ye are the fruits of my apostleship.

And I trust ye shall know - By proving yourselves, not by putting my authority to the proof.
