Your mentioning you are a Christian, Greg, prompted my observation. I was thinking of a relative who is an Anglican priest. I have known him since birth. After Harvard Divinity he entered the ministry and seemed settled as a bachelor pastor when lo and behold, at 40 married a divorced parishioner whom , ahem, he had been marriage-counseling prior. He became the stepfather of tw0 (one special needs) and then the father of two more. One of his kids has just come out publicly as gay.
The effect of his life choices on him? Nothing, that I can see. He is the same well-balanced, energetic,cheerful, matter=of-fact, intellectual guy I have always known. He is busier now than ever, but seems to handle it easily.
Not making any special point here, but I have seen the same thing in others who have a central belief, be it atheist or environmentalist or anarchist or whatever. We shape our lives to our personalities.
