It is not expedient for me - There are several various readings on this verse which are too minute to be noticed here; they seem in effect to represent the verse thus: "If it be expedient to glory, (which does not become me), I will proceed to visions," etc. The plain meaning of the apostle, in this and the preceding chapter, in reference to glorying is, that though to boast in any attainments, or in what God did by him, was in all possible cases to be avoided, as being contrary to the humility and simplicity of the Gospel; yet the circumstances in which he was found, in reference to the Corinthian Church, and his detractors there, rendered it absolutely necessary; not for his personal vindication, but for the honor of the Gospel, the credit of which was certainly at stake.

I will come to visions - Οπτασιας· Symbolical representations of spiritual and celestial things, in which matters of the deepest importance are exhibited to the eye of the mind by a variety of emblems, the nature and properties of which serve to illustrate those spiritual things.

Revelations - Αποκαλυψεις· A manifestation of things not before known, and such as God alone can make known, because they are a part of his own inscrutable counsels.

That Man Hath no Good in Himself, and Nothing Whereof to Glory
Lord, what is man that Thou art mindful of him, or the son of man that Thou visitest him?(1) What hath man deserved, that Thou shouldest bestow thy favour upon him? Lord, what cause can I have of complaint, if Thou forsake me? Or what can I justly allege, if Thou refuse to hear my petition? Of a truth, this I may truly think and say, Lord, I am nothing, I have nothing that is good of myself, but I fall short in all things, and ever tend unto nothing. And unless I am helped by Thee and inwardly …

Extracts No. viii.
"In regard to the story reported among the Jews, respecting the body of Jesus, I admit there is a greater probability of there being such a report, especially if the body could not be found, and the apostles affirmed that he was risen from the dead, than there is that the resurrection, should be actually true: hence, perhaps, I was not so much on my guard in the expression as I ought to have been. What I particularly had in my mind was, that I might find it difficult to prove even the existence of …
