There are a few different views on this subject, and Im a firm believer in the pre tribulation rapture. We are the bride of Christ, and it would seem out of character for God to beat His bride for 7 years prior to the wedding in Heaven.
Ones belief on the timing of the rapture is not a salvation issue, and as I like to jokingly say “those who dont believe in a pre trib rapture, thats OK, I will explain it on the way up.
