You do know that's not a scripture on the rapture right? Look at the last word in that scripture:
Mark 13:25-27. The elects are gathered from
heaven.
You can't have a rapture gathering people from heaven. In a rapture, people go up, they don't come down.
The elects had been raptured pretrib:
Isaiah 26:19-21,
Hebrews 12:22-29 and awaiting in heaven in our eternal mansion built by God in a heavenly city built for us by God:
John 14:2,
2 Corinthians 5:1,
Hebrews 11:9-10,
Hebrews 11:16 until the end of the tribulation when Christ sends His angels to gather His elects from heaven. We return to earth to reign with Christ to take care of unfinished business over the next 1000 years to get everyone else spiritually prepared and ready for the eternal kingdom in
Revelation 21-22. By then, God's divine plan of redemption for the sin of mankind will be completed.
