Summary: The Bible tells us that the coming of Christ is imminent, which means that it could happen at any moment. So Paul teaches Christian to be ready and must expect at any moment that Jesus will soon return to the earth.
BE READY, JESUS IS COMING AGAIN!
“They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. ‘Men of Galilee,’ they said, ‘why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.”
Professor Charles Erdman points out that the doctrine of Christ’s return is fundamental, scriptural, and controversial. It is fundamental in that all true Christians believe that one day Jesus himself will return to the earth. It is scriptural in that our faith rests not in our dreams but in the clear revelation of God’s Word. It is controversial in that Christians have often differed among themselves regarding the details pertaining to Christ’s return.
In this message, I just want to ask one question: What will the Second Coming of Christ be like?
Let’s consider three answers to that question.
I. JESUS COMING WILL BE PERSONAL (v.11)
Acts 1:11 (quickview)  makes it clear that Jesus himself will one day return to the earth. It will be “this same Jesus” who is coming again. Twice in one verse Luke uses the word “same” to make it clear of His Second Coming. The same Jesus who left will one day return. And he will return the same way that he left.
In plain English, those words teach us that Jesus is coming back personally, literally, visibly and bodily. We can assume that his return to the earth will be no less amazing and no less surprising.
The truth is that the actual, historical figure who lived 2000 years ago on the other side of the world is returning to the earth one more time.
In 1800 William Miller predicted the return of Christ in 1844 All over the Northeast, half a million Adventists awaited the end of the world on April 3, 1843. Journalists reportedly some disciples were on mountaintops, hoping for a head start to heaven. Others were in graveyards, planning to ascend in union with their departed loved ones.
In 1992 Harold Camping predicted the end, again nothing happened and he changed his date to 1993 and then 1994.
In 1995, there was a person who announced that the Lord told him that He is coming on October 28. Later I learned that the leader was imprisoned for staffa because he used his employers money for his campaign.
I just want to give one comment. These groups—however were misguided—but were right about one thing. God in the person of Christ is coming back someday.
II. JESUS COMING WILL BE GLORIOUS (v. 9)
Acts 1 (quickview)  tells us that Jesus was caught up in a cloud and taken to heaven. The cloud that carried Jesus into heaven was no ordinary cloud but was in fact the same cloud that led Israel in the wilderness. It is the cloud that represents the glory of God. Luke 21:27 (quickview)  tells us that Jesus will return “in a cloud with power and great glory.”
There are differences surrounding Jesus first coming to his second coming. The first time Jesus came unnoticed into the world, the second time “every eye will see him” (Revelation 1:7 (quickview) ). In his first coming Jesus humbled himself, being born in a stable in Bethlehem. When he returns, he will come back as King of Kings and Lord of Lords. The first time he came he was judged and sentence by the people according to their wrong standard, but when he comes, he will judge every person according to God’s standard.
