This is what it means to me:
(When you get time, just go ahead and read the whole chapter of 1 Cor. 15!)
(19) If in this life only we have hope in Christ, we are of all men most miserable.
(20) But now is Christ risen from the dead, and become the firstfruits of them that slept.
(42) So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
(43) It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
(51) Behold, I shew you a mystery; We shall not all 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) So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
(55) O death, where is thy sting? O grave, where is thy victory?
(56) The sting of death is sin; and the strength of sin is the law.
(57) But thanks be to God, which giveth us the victory through our Lord Jesus Christ.
(58) Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
