Before entering the theme of the second coming of Christ it is extremely important to detail that there are events happening in the air before Christ actually reaches the ground.
This is what we call the Rapture of the church. The word rapture is used in the Latin Vulgate translation but later replaced in English by the phrase caught up in the 1611 version.
I make no attempt to specify order of events or activities. the Christian faith however does declare that the physical removal of believers from the physical planet Earth is a hope of our future and a fundamental of the Christian faith..
1 Thes 4:16 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.
Then shall two be in the field; the one shall be taken, and the other left.
Two women shall be grinding at the mill; the one shall be taken, and the other left.
I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
Lu 17:34 I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left. 35 Two women shall be grinding together; the one shall be taken, and the other left. 36 Two men shall be in the field; the one shall be taken, and the other left. 37 And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
“Body” is a σῶμα, or an actual physical, tangible and solid body.
Ac 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judæa, and in Samaria, and unto the uttermost part of the earth.9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. 10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; 11 which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
1 Cor 15:50 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?
