Albert Barnes Commentary John 8:21

"He said therefore again unto them, I go away, and ye shall seek me, and shall die in your sin: whither I go, ye cannot come." — John 8:21 (ASV)

I go my way. (See Barnes on John 7:33).

You shall die in your sins. That is, you will seek the Messiah; you will desire his coming, but the Messiah that you expect will not come; and, as you have rejected me, and there is no other Saviour, you must die in your sins. You will die unpardoned, and as you did not seek me where you might find me, you cannot come where I will be. Observe:

1. All those who reject the Lord Jesus must die unforgiven. There is no way of pardon but by him. (See Barnes on Acts 4:12).
2. There will be a time when sinners will seek for a Saviour but will find none. Often this is done too late, in a dying moment, and in the future world they may seek a deliverer, but not be able to find one.
3. Those who reject the Lord Jesus must perish. Where he is, they cannot come. Where he is is heaven. Where he is not, with his favour and mercy, there is hell; and the sinner that has no Saviour must be wretched forever.
