In verses 50-53, he began by summarizing what he had been saying. We must be changed. We must receive a new body. God revealed to Paul the wonderful truth that a day is coming when the trumpet of heaven will sound, which will signal the return of Jesus Christ. The sting of death is sin, and the strength of sin is the law.
Death is swallowed up in victory.
It will be gone. After this exultant expression of resurrection triumph, Paul taunted death. The sting of death is sin because it is through sin that death came into the human race, and it is the awareness of sin that can make death a frightening experience. But in our place, Jesus Christ fulfilled the law by obeying it perfectly, and through His death He both paid the price for our sins and broke death's power. He won the victory over sin and death.
