As a teenager, I remember reading an account of the attempted assassination of Ronald Reagan; one of the most stunning aspects for me to think of was a bodyguard (or three) intentionally throwing himself across the President's body to act in a positive way as a human shield. (video here, a little blood shown) We've heard about 'taking a bullet for someone'... But what if President Reagan had seen the danger to one of his guards or aides and thrown himself across them to protect them instead? Rash, huh? Wrong priorities, etc...
God our Shield: Genesis 15:1; 2 Samuel 22:31; Psalm 7:10; Proverbs 30:5, etc.
