What would happen if you start to believe in God after Rapture

I get the rapture is a newer type of term. But 1 Thessalonians 4:13-18 does explain believers would be called up which normally got called rapture by what I hear

I see a lot of stuff lately that points to Rapture being September 11, 2026.

I originally accepted Christ as Lord and Savior when I was 14 but I feel at the time I was just too young to fully understand and didn't do much research. Around a year and half ago, I walked away when there was something in the Bible that I couldn't agree. IDK if it's my autistic part of my mind but if there is something that make no sense, I normally walk away.

Anyways, I recently discovered the Bible is still true and starting to get back. Is still difficult though.

But just now I'm starting to notice a lot of signs that points to Rapture happening on September 11, 2026.

I do believe the event would either be before the 7 years or half way through the 7 years.

What if you aren't called up and still have the 7 years or 2nd half of the 7 years, could you still repent and follow God? Could you still have another chance?
