So don't be deceived by the false doctrine of the Secret Rapture.The Second Coming will be seen by everyone so its kind of hard to have a "Secret Rapture" with everyone watching. So how will Christ return and how will the Second Coming unfold, well lets start at how he ascended:
And when He had spoken these things, while they beheld, He was taken up; and a cloud received Him out of their sight. And while they were looking steadfastly toward Heaven as He went up, behold, two men stood by them in white apparel; 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'. Acts 1:9-11
Jesus was taken up into heaven by a cloud, and He will return in the clouds. The clouds refer to the angels of God that surround Him. Jesus Himself promised that He would return with the clouds (the angels).
And then shall appear the sign of the Son of man in heaven; and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. Matthew 24:30
...the Lord Jesus shall be revealed from Heaven with His mighty angels. 2 Thessalonians 1:7
When the Son of man shall come in His glory and all the holy angels with Him, then shall He sit upon the throne of His glory. Matthew 25:31
...when He shall come in His own glory, and in His Father's and of the holy angels. Luke 9:26
Jesus return in the clouds will be visible to everyone on earth and will be any kind of secret, or only seen or experience by a select few. Christ also warned against false comings of Christ that would not be universally visible.
Behold He cometh with clouds, and every eye shall see Him... Revelation 1:7
Wherefore, if they shall say unto you, Behold he is in the desert; go not forth: behold, he is in the secret chambers, believe it not. For as the lightning cometh out of the east and shineth even unto the west, so shall also the coming of the Son of man be. Matthew 24:26,27
...they shall see the Son of man coming in the clouds of Heaven with power and great glory. Matthew 24:30
Jesus return in the clouds will great a audible sound so that everyone on earth know of his coming, not just a select few.
And he shall send His angels with a great sound of a trumpet and they shall gather together His elect from the four winds, from one end of Heaven to the other. Matthew 24:31
The Lord Himself shall descend from Heaven with a shout and the voice of the archangel, and with the trump of God... I Thessalonians 4:16
Jesus will return in the clouds while everyone sees and hears his Second Coming and the faithful, those that had died and those alive will be picked up and meet him in mid-air in the cloud of his angels. The redeemed (elect) will be gathered together by angels and taken up into the air to meet the Lord in the sky, the verses make clear it is not a secret rapture.
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. 1 Thessalonians 4:16,17
And He will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other. Matthew 24:31 NIV
At the second coming, Christ calls forth the dead and sends forth His angels to gather the elect, and together they meet Him in the air. Christ Himself does not come down to the earth - His feet do not touch the earth. His command to His angels is:
Gather my saints together unto me, those that have made a covenant with me by sacrifice. Psalm 50:5
The living righteous are changed in moments at the last trumpet. We cannot go to heaven with pain, sickness, disease, we will be transformed in a instance, all these things will be taken away. Our bodies will be changed into the likeness of His, incorruptible, and changed to immortal.
Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible has put on incorruption, and this mortal has put on immortality, then shall be brought to pass the saying that is written: 'Death is swallowed up in victory.' 1 Corinthians 15: 51-54
For our citizenship is in heaven, from which we also eagerly wait for the Saviour, the Lord Jesus Christ, who will transform our lowly body that it may be fashioned like unto His glorious body... Philippians 3:20, 21
Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He shall appear, we shall be like Him . . and every man that hath this hope in Him, purifieth himself, even as He is pure. 1 John 3:2,3
He will swallow up death in victory, and the Lord God will wipe away tears from off all faces; and the rebuke of His people shall He take away from off all the earth; for the Lord has spoken it. And it shall be said in that day: 'Lo, this is our God; we have waited for Him, and He will save us. This is the Lord; we have waited for Him; we will be glad and rejoice in His salvation.' Isaiah 25:8,
