Our family friend is in the hospital and is dying. He is an atheist and not the nicest person in the world.?

Our family friend is in the hospital and is dying. He is an atheist and not the nicest person in the world. He had the women he was involved with have a couple of abortions, he believes in evolution, etc. How can I convert him to our non-denominational christian faith (we are reborn evangelicals), and help him transition into the next life with pion and love for our lord jesus christ, and more importantly god. I am hoping that by him converting at this point in his life we can reach the rest of his family and get them to be as dedicated to christ as the rest of us (like my family and other members of our church). Thank you in advance for your time, consideration, and prayers..we will try to reach another sinner with your help.
