1 Thessalonians 4:12 (KJV)

For God hath not called us unto uncleanness, but unto holiness.

He therefore that despiseth, despiseth not man, but God, who hath also given unto us his holy Spirit.

But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.

And indeed ye do it toward all the brethren which are in all Macedonia: but we beseech you, brethren, that ye increase more and more;

And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;

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.

For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.

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.

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:

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.
