Lloyd-Jones discusses overcoming the world. He points out that cloistering oneself off from the world, similar to what the monastic movement did, is ultimately not the answer:
... the world is not only outside us with its sin and temptations and attractions, but it is also inside us -- the flesh, our own unregenerate nature. So in a sense, it is almost childish to think I can overcome the world by taking myself out of it, because when I have gone into my cell the world is still within me; so my attempt is to escape by physical means is almost doomed to failure. This is something that we all must now from experience. We have all been alone, we have all been isolated at certain times; the world has not been there to tempt us. But was all well with us? Were we perfectly happy; were we free from temptation; was the mind and the outlook and the spirit of the world entirely absent? God knows that such is not the case!
You can go away and spend your day on top of a mountain, but you cannot get away from the world; it is in you, so that any retirement to a monastery, or becoming an anchorite or a hermit, is doomed to failure. That is the whole story of Martin Luther; look at the excellent monk in his cell -- fasting, sweating, praying, out of the world in a sense, and yet finding that the world was in him and he could get no peace. Therefore, withdrawal from the world and from society does not get rid of the world in the New Testament sense of the term.
