Dr. Mark Hitchcock would like to call one as the Rapture and the other as the Return. For the Rapture, Jesus comes for His saints, an event of His grace to us. For the Return, Jesus comes back with His saints, an event of judgment.
The rapture can come at any time. It is a sign-less event.
On the other hand, the return will be preceded by many signs during the 7 years of trials and tribulations.
"Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war." - Rev 19:11
There are many different interpretations as to whether the descriptions in the book of Revelations are symbolic or literal, especially in chapter 19 where it talks about Jesus riding on a white horse. Regardless of one's interpretation, someone coming on a white horse speaks volumes in terms of power and authority.
Jesus Christ returns at the end of the tribulations period. He is coming back to rule and reign. And for those who have known Him, they will also be coming back with Him. It is the greatest event in history.
We need to live today in light of the fact that we are
going to come back as a holy army with Him.
