[Ali Imran]

The thief on the cross also granted paradise first bef he died 

Was he told that Jesus would die for his sins? No, he wasn't. And yet, he was saved according to the Gospel.

So apparently, you don't have to believe Jesus's death will pay for your sins in order to be saved, like that thief.

And also, you don't have to believe Jesus is God in order to be saved, like in Acts 2.
