Preferences, convictions, and CONVICTIONS

I can't recall from whom I first heard it...

"A preference is something you'll argue about; a conviction is something you'll die for."

Good saying.

But I've added to it...

"A preference is something you'll argue about; a conviction is something you'll die for; a thought-out, prayed-out Biblical conviction is something you'll let your family die for."

That last list is very short.

I wonder, do you agree?

And, of so, what's on your "let your family die for" list???
