1 Corinthians 15:1-5; 1 Thessalonians 4:16-17

1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;

2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.

3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;

4 And that he was buried, and that he rose again the third day according to the scriptures:

5 And that he was seen of Cephas, then of the twelve:

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.
