Revelation 1 Part 1

  7“Look, he is coming with the clouds,”1:7 Daniel 7:13
and “every eye will see him,
even those who pierced him”;
and all peoples on earth “will mourn because of him.”1:7 Zech. 12:10
So shall it be! Amen.
8“I am the Alpha and the Omega,” says the Lord God, “who is, and who was, and who is to come, the Almighty.”

Daniel 7:13 “In my vision at night I looked, and there before me was one like a son of man,[a] coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence.

Zech. 12:10 “And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and supplication. They will look on me, the one they have pierced, and they will mourn for him as one mourns for an only child, and grieve bitterly for him as one grieves for a firstborn son.

Jesus is coming back again!  He promised He would, and John is reminding us of this.  He's also reminding us that this has been foretold from the beginning; that a Savior would come for us, would die for us, and would return again.

Jesus' return will be seen by everyone, including the ones that 'killed' Him.  

"all the peoples on earth "will mourn  because of Him"
Why might this be?  My first thought is that I'd be happy to see Him, but it doesn't take long to realize that I too would feel the full weight of my sin when I see it in the light of Jesus.  What if I'm not here though?  The rapture occurring ahead of time would mean that there would be nobody on earth that would be happy to see Jesus return when He does come back.

Our pastor doesn't believe there will be a rapture, but he seems to be in the minority on this.  But because he doesn't think this will happen, now I'm not sure.  This verse seems to state that there will be no lovers of Jesus here when he comes back.  Maybe we would mourn because of those we love that do not love Him?
