C.S. Lewis quote-of-the-week on those who have heard (explicitly) about the grace of God
"I wonder whether people who ask God to interfere openly and directly in our world quite realize what it will be like when He does. When that happens, it is the end of the world. When the author walks on the stage, the play is over...It will be God without disguise; something so overwhelming that it will strike either irresistible love or irresistible horror into every creature. It will be too late to choose your side. There is no use saying you choose to lie down when it has become impossible to stand up...Now, today, this moment, is our chance to choose the right side." (Mere Christianity, Book 2, chapter 5)
This quote also speaks to "theodicy"-- why God seems to tolerate evil rather than showing up at any given point in time to smite it. It reminds me of a great quote from my brother-- where he noted that when people want God to show up to deal with evil, it's never with respect to the evil they perpetrate!
