On Facebook, it gives you a flashback of your memories on specific days. It just randomly pops up. Today, mine popped up to show me what I posted today in 2011. It is as true now as it was then:
"I personally believe in Jesus Christ. One person on Facebook has challenged all believers to put this on their wall. The bible says, "If you deny me in front of your peers, I will deny you in front of my father." (Matthew 10:33) If you love God and you are not afraid to show it, re-post this."
