how do you prove God to a non-believer?

First of all, you don't have to prove anything to non-believers. your belief is private and intimate and your believe don't have to go down because others don't believe. it is something deep between you and god. it is intimate connection between you and god. that is one point. if you want to spread the godness of god around you first have to be firm with your believe, knowing that the non-believer won't influance you to drop your faith in god. so you have to be strong enough in your believe before you start spreading god words. To your specific question, I think you have to tell him or her to look around in the wonderful things god created, no genius alive ever created something as close to something beatiful and as thoughtfull like the creation of god. most of the non-believers feels that because bad things are happening to them or if nothing good happening to them there is no god. so you have to tell the non believer that he has to look what he done in his life, every day to see what he did, what was the bad things or mistakes he made and that way he will see that not god is doing the wrong for him, only himself with a free will, the wonderful thing god gave him so he could do what ever he choose in life and will not feel ashame that god gave him free present.

hi junko, I think the person should be a empty cup.. if he dont believe in god no problem but he should be open to listen.. then only you can make him understand the glory of god.. Ask him what he always wished and want it to get.. tell him that pray and get it.. thanks hope that person is blessed with gods will.
