How do we get into heaven?

Ok so everyone says it’s Jesus that got you into heaven and you have to believe in him. It’s not your good works or deeds but Jesus so tell me why the entirety of James 2 is telling us that faith without deeds is dead? I just don’t get how God loves us all but then he sends you to hell for not believing in Jesus if he loves you then why does that matter? He loves you unconditionally until you die? How doesn’t he know you if he made you and is able to see every single one of your thoughts? And what kind of deeds? Does this mean anyone who doesn’t attempt to pray every single day, praise consistently, and always repent and change is going to hell? I am not even trying to debunk Christianity rn I just want answers because I thought God loves earth so much that he sent his one and only son to pay for our sins. If our sins are paid why are we still going to hell. That’s it does anyone have answers?
