I've been thinking about your website for awhile and how it relates to the Christian Market. Then it dawned on me the other day while in a bible study... I came across James 4:14 (Amplified Bible) –
14Yet you do not know [the least thing] about what may happen tomorrow. What is the nature of your life? You are [really] but a wisp of vapor (a puff of smoke, a mist) that is visible for a little while and then disappears [into thin air].
I also remember that in the "old" days - Shakespearian times if will, they often kept a skulls around in plain view as a reminder that life is fleeting - we are only here temporarily. It's certainly nothing to be afraid of. I hope this helps!
