God's favorite color

SB asked Jack last week one of those questions that we as parents love to field. Not the "where do babies come from" variety of question, although I've certainly handled a few of those. This time, her question was much deeper.
SB: "Daddy, what is God's favorite color?"
Jack: "I don't know, Sarah Beth."
SB: "Ok, well I'll just ask Caroline."

Caroline is Sarah Beth's slightly older cousin, whom SB adores. She tells SB lots of things, many of them related to Justin Beiber.

Jack: "If I don't know what God's favorite color is, what makes you think Caroline knows?"
SB: "Caroline just knows those kinds of things.
Jack: "Well, if Caroline says she knows God's favorite color, then she is LYING. It's IMPOSSIBLE to know those kinds of things.

SB was quite taken aback at Jack's stern response. She thought for a minute and then said "Okaaaaaaay....well, I'll...deal.... with that.....tomorrow."

A few days later, we had the opportunity to ask Caroline. She didn't miss a beat. "Of course I know God's favorite color. It's white because He washed our sins away and now we're white as snow."

Turns out, she does know those kinds of things.
