This is one of those constantly recurring threads. Which is fine, as there are constantly new people here.
You can simply search "what is the difference between the Rapture and the 2nd Coming" and get plenty of articles, videos, and pics like this one. There's a whole lot more Scripture that differentiates the two events, but this is a good start:
There's even more than this:
Acts 1:11 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.
At the second coming of Christ Jesus, He will NOT be coming back in like manner as was the manner of His departure and that will be in the rapture.
In His departure, he was showering them with blessings and instructions. At His Second Coming, He will be coming in wrath and destruction. The very character in stark contrast between the two appearances of Christ, the rapture and the Second Coming, plus His garments being spattered with the blood of His enemies at His Second Coming, the contrast becomes even more pronounced.
Revelation 19:11, 13, 15
11 And I saw heaven opened, and behold a
white horse; and he that sat upon him [was] called Faithful and True, and in righteousness he doth
judge and make war. ...
13 And he [was] clothed with
a vesture dipped in blood: and his name is called The Word of God. ...
15 And out of his mouth goeth
a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and
he treadeth the winepress of the fierceness and wrath of Almighty God.
One doesn't have to be a theologian to see that Christ's departure and the like manner of His coming for us in the rapture are polar opposites in relation to His Second Coming where His feet will touch down upon the earth, make war in the fierceness of His wrath, have a vesture of blood, smiting the nations...it escapes me how anyone could ever think they are one and the same, or that He had already come in 70 AD as is believed by most preterists.
Yes, the dead in Christ will be raised first. No question about that.
