My experience:
A while ago (several years ago) I did not believe in God. Any God. Hindu, Catholicism, Judaism, Protestant, I explored various religions but finally decided there was no God, based on what I learned and saw in the various religions and life around me. But then -- but then -- something happened and I "needed" God, a higher power. But I had no faith. I didn't pray because -- I didn't believe in God. Yet I asked a minister how can I believe in God? He said, "Faith is a gift of the spirit." I told him that I don't have faith. He said, "Faith is a gift of the spirit that only God can give." And I said, "But I don't believe in God." He again repeated that only God can give me this gift of faith. So I realized the conversation was over, and exited the conversation. But that night I prayed for the first time in a long time. Not for happiness but for faith, I prayed, "Oh, God, if you're there, give me this gift of faith." Things happened after that. I fought, i argued. But here I am with faith. Thankful. Did my life become better? Yes, indeed, just as Jesus said.
