[1Co 15:49-57 KJV] 49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly. 50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption. 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.
[Jhn 14:2-4 KJV] 2 In my Father's house are many mansions: if [it were] not [so], I would have told you. I go to prepare a place for you. 3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, [there] ye may be also. 4 And whither I go ye know, and the way ye know.

[1Th 4:13-18 KJV] 13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. 14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15 For this we say unto you by the word of the Lord, that we which are alive [and] remain unto the coming of the Lord shall not prevent them which are asleep. 16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive [and] remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.
