I disagree 1th 4 :& says all that it says this
1Th_4:17 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.
You also need 1Corinthians 15:51-57 to go along with what is said in 1Thessalonians 4:13-18 to have the whole transpiring of what happens to us when Christ returns, what we will look like, 1John 3:1-3, and when He will return, John 6:40, even though we not know the day or the hour of His return.
1Corinthians 15:51 Behold, I show 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.
