1 Co 15:56 The sting of death is sin...
By "death" here is meant the death of the unsaved, those whose sins are unforgiven.
By "sting" here is the power to harm.
The death of the unsaved has a sting. It is harmful. Because unforgiven sins will always be met with divine judgment after death. On the other hand, the death of the saved sinner is gain.
Php 1:21 For to me, to live is Christ, and to die is gain.
The death of the saved has no sting in it. Death for the saved sinner is described as being asleep in Jesus. It carries a blessed prospect of being awakened in a glorious resurrection at the Rapture.
1Th 4:14 For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus.
