In Hebrews 12:1, he says, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us. Notice that it is not just sin that we lay aside. That should be obvious. But he also says to throw off anything that weighs us down and interferes with our spiritual race. Our race is against our own nature rather than against someone else. We are our own most formidable opponent. Laying aside every weight takes careful evaluation of each aspect of our lives, as we touched on, to see whether it is helping us in our calling or holding us back.
