I Corinthians 15:50-58
“50 Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable. 51 Behold, I tell you a mystery; we will not all sleep, 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 must put on the imperishable, and this mortal must put on immortality. 54 But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, “Death is swallowed up in victory. 55 O death, where is your victory? O death, where 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 brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord.”
