Fourthly, world conformity enters the picture here. Believers still have a desire for the things of the world under the cover and pretense that they are lawful, necessary, and fitting – even though the real motive is love for the world. The world and the spirit are enemies, and the one is always intent on expelling the other; they are a mutual impediment to each other, and therefore we must either fully yield to the world, or must yield fully and entirely to grace. As long as we halt between two opinions, and as long as we attempt to join together Christ and Belial, so long shall we make no progress. A bird which as been fastened to the earth will fall back to the earth when it wants to fly upward. Thus, he who wishes to fly heavenward must divorce himself from the world.
