Write what you know, a writing sage has admonished. If I stuck to writing what I absolutely knew to be true, my posts would be quite short--oh wait, they are short. Maybe that's why so many of my posts cover travel. Post a pretty picture or two and move on. The Truth is that I have many opinions and know little incontrovertible Truth. That goes for any possible statement regarding religion or the nature of the Universe. We choose what to believe and sort ourselves into different camps, often as a result of our personal circumstances. Some of us "know" that God exists, has a gender or doesn't, is merciful or wrathful, loves everyone or hates gays, speaks to us through the Bible, or doesn't exist at all. We "know" that capital punishment deters murderers or is cruel and unusual. We "know" that figures don't lie or that liars do figure. We "know" these things because our parents told us (and we know they wouldn't lie) or God (if such there be) help us, we read it on the Internet.
My own opinions are based on emotion or on information I choose to trust. If the world only trafficked in absolute facts, it would be unable to function.
So I don't know much with certainty, and that's the Truth.
