I'm with Phbrown on this one. I don't believe in chance. In fact, I'm an extremist when it comes to this subject. I believe even the littlest of things are planned, ordained, or allowed by God. If I get a run in my pantyhose, or miss an important phone call, get pulled over by a police officer, oversleep, lose a $20 bill, can't find that scripture I'm looking for, can't remember who I was about to call... it's all for a reason.
By the way, that line of thinking really helped me to change my mind about what stresses me out and what doesn't. I believe everything happens for a reason, and looking at it that way means that 95% of what used to bother me, now doesn't - because I know it's for purpose.
