2 Corinthians 3:16 - Matthew Poole's English Annotations on the Holy Bible

When it shall turn, may be understood of the whole, or of the generality (at least) of the Jews; when they shall be converted to the faith of Christ, or when any particular person shall be converted to Christ, then the veil shall be taken away; not the veil with which God covered and veiled the mysteries of the gospel, (that was already taken away upon Christ's coming in the flesh), but the veil of blindness, which they had drawn over their own souls. Though the light of the gospel shineth clearly, and Christ be unveiled, yet until men, by a true faith, receive Christ, and turn from sinful courses to the obedience of the gospel, they see little or nothing of Christ. The taking away of this veil, and the turning to the Lord, are things done in souls at the same time; therefore nothing is to be concluded here, from the apostle's naming the removal of the impediment, after the effect of which that is a cause.
