I rely on faith because sometimes it's all you have. Life sucks at times. Mostly about loss, bad people getting what they want, cheating, scamming, abuse, neglect, lies, manipulations , corruption and failures, but there are some good things. That bad people get away with things while the decent hurt, shows me more that's is still a test. You can know most everything but it may not help you, and you can know a little, and believe, and it will be all good and no pain when you get to heaven. Everyone comes from their own share of hell and good. It's what you do with it that counts, as no one has all the answers. Temporary life here, forever in heaven. That people can go through hell on earth and still believe in God, is exactly what I would see as a test.
