Jesus said, "I tell you that in the same way there is more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent."
Christians apparently are enjoined to share this attitude.
That said, I doubt that celebration is the reason that people bring this up here. I stand by the point of MY post, which is that faith needs no celebrity endorsement, and any posting to that effect is converting folks who are not going to be long with one religion, anyway.
"Look, Jessica Simpson's Christian! I think I'll start going to prayer meetings again!"
I just don't see it. If I want to welcome Flew to the flock, I'll buy him a frosty one. Trumpeting it to the secular world reeks of cola wars.
