will jesus really rise from the grave ?

He already has risen and is living in Heaven at the right hand of God. Now, we believe that He will come again, but he won't have to rise again, since he's already done that. i take from your question that you are not a christian? do you have access to a bible? I could point verses out for you to read that talks about the resurrection and also that Christ will come again, and if you've not accepted Him as your Savior, you will be left.
