C. S. Lewis
When the author walks onto the stage, the play is over. God is going to invade, all right; but what is the good of saying you are on His side then, when you see the whole natural universe melting away like a dream and something else comes crashing in? This time 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 then to choose your side. That will not be the time for choosing; It will be the time when we discover which side we really have chosen, whether we realized it before or not. Now, today, this moment, is our chance to choose the right side.
