In 2 Thes ch 2 if you read it over and over you will see that the Antichrist is not revealed till after the rapture...and Elijah to come in Mal 4:5-6 must come before the rapture and restore all things...which he cannot do during the 7 year tribulation when the world will be blow apart....
2 Thessalonians 2 not say antichrist reveal after rapture
It reverse
It say rapture not happen before man of sin or antichrist reveal
2 Thessalonians 2
2 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
