Some modern theologians want to see many of the miracles in the Bible as metaphors, not as realities, they even see the resurrection as a metaphor alike and therefore cannot see the power found in it.
In order to talk about resurrection, the first thing we should do is talk about the person of Christ, then, He, in great power and glory, rose again on the third day and left the grave empty. And that Christ was resurrected is what keeps the church with a living hope that it will also be resurrected on the last day.
The great hope of the church of Christ is the resurrection, that this mortal body will be clothed with immortality:
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?
1 Corinthians 15:51-55
