Are there any verses in the Bible besides 1 Thessalonians 4:17 that support the doctrine of the rapture?
I have yet to find a difference in events that take place in 1 Thess. 4:17 and events that other scripture speaks of when referring to Christ's 2nd coming (as in Matt. 24) (if anyone can point any differences out, please do), so I'm not certain about that verse.
However, I think that this verse might:
Jesus tells us this after telling us about end-times 7 year tribulation events. I would say He could've meant to have the strength to escape the desolation of Jerusalem, but what He says to escape from is coming upon on the entire earth. Perhaps by strength, He means the strength to endure our sinful carnal urges (as in Rev. 3:10).
"[Be careful because that day will come upon you like a trap, for it will come upon the entire earth.]" We will/would be trapped with nowhere to escape to..except into His presence.
Another verse that might speak of rapture:
Matthew 13:30 and the book of Joel. Search for the word harvest in the Bible. Many references to harvest in the Bible are referring to the separation of weeds and the wheat which represents the difference between the unsaved and the saved during the Lord's Day.
There's also Matthew 24:40-42
and it's friend Luke 17:34-35
so long as you leave off the next verse
Which rapture folks might be likely to do.
It kind of leaves you thinking that the lucky one is the one who is left, not the one who was taken and eaten by a vulture. If this were pointing to a rapture, the one who was left would be the one eaten by a vulture.
