1 Corinthians 15.51-58
51 Listen, I will tell you a mystery! We will not all die,[a] but we will all be changed, 52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. 53 For this perishable body must put on imperishability, and this mortal body must put on immortality. 54 When this perishable body puts on imperishability, and this mortal body puts on immortality, then the saying that is written will be fulfilled:
‘Death has been swallowed up in victory.’
55 ‘Where, O death, is your victory?
Where, O death, is your sting?’
56 The sting of death is sin, and the power of sin is the law. 57 But thanks be to God, who gives us the victory through our Lord Jesus Christ.
58 Therefore, my beloved,[b] be steadfast, immovable, always excelling in the work of the Lord, because you know that in the Lord your labour is not in vain.
