I am going deer hunting in Eastern Oregon this weekend. I own a 300 Weatherby Magnum. It is a nice gun, and it shoots well. When I was a kid, my Dad would have me dry fire my rifle a hundred times a day, the week before we went hunting with a spent cartridge in the chamber. He said that I needed to be able to shoot and have my eyes open when the gun fired, with no sign of a flinch or jerk. He said that when I dry-fired it with no flinch and my eyes were open and fixed on the target, whatever it was that I was aiming at out the window, I would know whether I would have hit it or not. He said it was actually better practice than shooting live ammunition, and it was free. 300 Weatherby shells are very expensive, so the free part is a great. He said practice until you hit what you look at every time.
The Bible mentions focusing many times. We are to focus on heaven, not on this earth or life. We are to focus on Jesus and work at pleasing Him, not on the people around us. We are to focus on the finish line, the day we stand at the judgment seat of Christ, so we will run the race set before us with faithfulness and endurance. What we set our eyes on is what we think about. What we set our eyes on determines what we become as a person in character. What we set our eyes on is where we end up in life. What we set our eyes on determines what we accomplish with our lives. Focus is the key to self-control. Focus determines whether we will succeed in life or not. Focus.
