From 1st Corinthians 15
Christ’s Resurrection Guarantees Ours
20 But as it is, Christ has been raised from the dead, the firstfruits of those who have fallen asleep.
21 For since death came through a man, the resurrection of the dead also comes through a man.
22 For just as in Adam all die, so also in Christ all will be made alive.
23 But each in his own order: Christ, the firstfruits; afterward, at his coming, those who belong to Christ.
24 Then comes the end, when he hands over the kingdom to God the Father, when he abolishes all rule and all authority and power.
50 What I am saying, brothers and sisters, is this: Flesh and blood cannot inherit the kingdom of God, nor can corruption inherit incorruption.
51 Listen, I am telling you a mystery: We will not all fall asleep, 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 incorruptible, and we will be changed.
53 For this corruptible body must be clothed with incorruptibility, and this mortal body must be clothed with immortality.
54 When this corruptible body is clothed with incorruptibility, and this mortal body is clothed with immortality, then the saying that is written will take place:
Death has been swallowed up in victory.
55 Where, death, is your victory?
Where, 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 dear brothers and sisters, be steadfast, immovable, always excelling in the Lord’s work, because you know that your labor in the Lord is not in vain. source

An excerpt from the link above: no I’m not kidding. “Where Easter is concerned, however, we have confused a pagan ritual with First Fruits. Each spring, the Babylonians saw the genuine first fruits and assumed it would be a fine time to ask their goddess, Ishtar (Easter), for new babies. They worshipped the things in nature which represented fertility, such as the rabbit and the egg. The people wore new costumes, in keeping with the new buds on the trees and shrubbery. Today, we continue the Babylonian rite with our Easter Bunny and our painted eggs and our new outfits for the Easter Parade. An egg hunt, of course, represents the attempt to conceive a baby.”
