Text: First Corinthians 15, 51-58.

51 Behold, I tell you a mystery: We all shall not sleep, but we shall all be changed, 52 in a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.53 For this corruptible must put on incorruption, and this mortal must put on immortality.54 But when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall come to pass the saying that is written, Death is swallowed up in victory.55 O death, where is thy victory? O death, where is thy sting? 56 The sting of death is sin; and the power of sin is the law: 57 but thanks be to God, who giveth us the victory through our Lord Jesus Christ.58 Wherefore, my beloved brethren, be ye stedfast, unmovable, always abounding in the work of the Lord, forasmuch as ye know that your labor is not vain in the Lord.
