“Dying saints are justly to be envied whilst living sinners are to be pitied.” Critical and Explanatory Commentary, Vol. I
This is the first time I read the commentary and then looked up the verse. Usually one verse seems to stand out.
When I read this line, I thought of those who have passed on to eternity. From the great cloud of witnesses, (Hebrews 12:1), they see our suffering and know from experience it only lasts a short time compared to eternity.
Their time of suffering is over, forever. Their race is run. As believers in Jesus Christ they have only joy in heaven.
Those to be pitied are sinners, anyone who rejects Christ, because they have more suffering in store for them in eternity.
Jeremiah 22:10, “Weep not for him who is dead nor bemoan him; but weep bitterly for him who goes away [into captivity], for he shall return no more nor see his native country [again].”
