The Apostle concludes the chapter with Isaiah's prophetic words that one day "death will be swallowed up in victory," that is, it will be conquered utterly.
He also uses the words of the prophet Hosea, that the sting will be torn from death and Hades will be deprived of its victory.
After thanking God for the victory over death and sin granted to us through the Lord Jesus Christ, the Apostle turns to the Corinthians with this instruction.
"Therefore, my beloved brethren, be steadfast, immovable," that is, in faith and Christian life. "Always abound in the work of the Lord," that is, in the work of salvation.
"Know that your labor is not in vain before the Lord," for there is a resurrection of the dead and there is a future life.
