Albert Barnes Commentary 2 Corinthians 3:16

"But whensoever it shall turn to the Lord, the veil is taken away." — 2 Corinthians 3:16 (ASV)

Nevertheless. This is not always to continue. The time is coming when they will understand their own Scriptures, and see their true beauty.

When it shall turn to the Lord. When the Jewish people will be converted. The word "it" here refers undoubtedly to "Israel" in 2 Corinthians 3:13; and the sense is that their blindness is not always to remain; there is to be a period when they will turn to God, and will understand his promises, and become acquainted with the true nature of their own religion. The apostle has discussed this subject at much greater length in Romans 11 (see the notes on that chapter).

The vail shall be taken away. They will then understand the true meaning of the prophecies, and the true nature of their own institutions. They will see that they refer to the Lord Jesus, the incarnate Son of God, and the true Messiah. The genuine sense of their sacred oracles will break upon their view with full and irresistible light. There may be an allusion in the language here to the declaration in Isaiah 25:7: And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations. This verse teaches:

1. That the time will come when the Jews will be converted to Christianity, expressed here by their turning to the Lord, that is, the Lord Jesus .
2. It seems to be implied that their conversion will be a conversion of the people at large; a conversion that will be nearly simultaneous; a conversion en masse. Such a conversion we have reason to anticipate of the Jewish nation.
3. The effect of this will be to help them understand the true sense of their own Scriptures, and the light and beauty of the sayings of their own prophets. Now they are in deep darkness on the subject; then they will see how entirely they meet and harmonize in the Lord Jesus.
4. The true and only way of having a correct and full meaning of the Bible is by turning to God. Love to him, and a disposition to do his will, is the best means of interpreting the Bible.
