In a bible study yesterday the subject of courage came up. Someone mentioned the courage of David versus Goliath. So the question was asked "How were the people meant to be brave in the face of Goliath and the Philistines?"
One person answered: "Look at David!"
Good answer. Instant bravery, just look at your King's victory. You don't even have to think about it. Once you see the Giant fall there are no further mental processes required, no negative automatic thoughts to conquer, no re-framing of core-beliefs. You see the victory of your Champion and you will be brave.
