If I Reject Islam, Can I Still Go to Paradise?

“What if a non-Muslim, who does not necessarily believe in Islam but does believe that God exists, what if his actions and deeds have been good and well-intentioned in this world? Will he still be admitted into Jannah? Or will he be thrown into Hellfire just because he didn’t believe in Islam even though everything else that he did in this life turned out to be good and he’s remembered for that?” Also, how do we explain the materialism of Jannah to non-Muslims?
