When I took my ccw class we did an exercise like this. We had our gun at the ready position. It was in a two handed hold but down at waist level and pointed downward at a 45 degree angle. We had an 8 1/2 x 11 sheet of paper 21 feet in front of us. There was a person 21 feet to our right. A whistle was blown. You had to put 2 rounds into the paper before the guy with the knife reached you. I shot from the ready position. I put both rounds on target. No one that brought their gun up to eye level to use their sights made it. Everyone of them was touched with the knife. Very eye opening experience. I had never even thought about it until that day.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
