Jesus talked many times about coming again - i.e., a “second coming” - not sure why this is difficult to understand. As for rapture, see the following explanation - it is just a transliteration of a Latin word for a Greek phrase in the New Testament
There are too many people that fall for the secular worlds uninformed arguments - a little Google searching can help clear things up.
For the record, the word “rapture” comes from the Latin word rapturo, which is a translation of the Greek verb “caught up” that’s found in 1 Thessalonians 4:17. You can call it the “pre-trib rapture,” the “pre-trib rapturo,” or the “pre-trib caught up” - it’s all the same thing.
These 144,000 are called the “firstfruits to God and to the Lamb.” Rev. 14:4. If we are not the firstfruits (and we are not), then this had to happen before today or we have no hope. These are the Jews who survived the persecution of the early church - the firstfruits of salvation. And we, also, will follow.
I have no problem with “the rapture”, just with the belief that it sets up another new beginning. I believe that the work of Jesus is complete and needs to new phase. Satan has been thrown out of Heaven and is not longer the accuser before God.
