I think we all hv the same chance of Salvation whether we are pretribber or a postribber, if one of these is wrong we pray Jesus will teach the wrong one.
Have you ever studied the last verse of Hebrews 9? Read it in every translation you can find: they all give the same idea. He came once to solve the sin problem. He will come again, but the next time, NOT to solve the sin problem, but for a different purpose. Young's literal does a good job:
So also the Christ, once having been offered to bear the sins of many, a second time, apart from a sin-offering, shall appear, to those waiting for him -- to salvation!
CJB) so also the Messiah, having been offered once to bear the sins of many, i will appear a second time, not to deal with sin, but to deliver those who are eagerly waiting for him.
(CSB) so also the Messiah, having been offered once to bear the sins of many, will appear a second time, not to bear sin, but to bring salvation to those who are waiting for Him.
(ESV) so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.
(LEB) thus also Christ, having been offered once in order to bear the sins of many, will appear for the second time without reference to sin to those who eagerly await him for salvation.
(NIV) so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
Do you see what is common in all of these translations? He will appear to those who are eagerly awaiting Him! So what if someone imagines they will see the Beast first? Will they be eagerly awaiting Him? I think this is why God has given us a bible where we are told to watch 14 different times!
