Any Advice on Doubts?

Anyone have any advice on having doubts? I’m a Christian and will be fairly logical most of the time but sometimes I’ll read other religions like Qu’ran quotes online about how unbelievers will wish that they had submitted on the day of the judgement and it really really scares me. I just sort of get that ‘what if?’. I think a lot of it is to do with how empathetic and how well I put myself in others’ shoes, how different would it be from myself, a Christian to go back and read my Bible and everything being fine and dandy, compared to a Muslim going back to read the Qu’ran to back themselves up. I don’t know, I’m just really scared of the idea of hell, I suppose a good thing but I’m just scared of making the wrong choice. Thank you, blessings
