James 1:27 Pure religion, and undefiled before God and the Father ..... Notice this, that it does not say to keep out of the world, but to keep unspotted from the world. 
Christ prayed for His disciples:
John 17:15 I pray not that You should take them out of the world, but that You should keep them from the evil. They are to be in the world, but not of it.
John 17:15 I pray not that You should take them out of the world, but that You should keep them from the evil. They are to be in the world, but not of it.
But a man may be of the world in a monk’s cell or in a cave, just as much as if he were in a place of business.
1 John 2:16 The lust of the flesh, the lust of the eyes, and the pride of life… These are of the world.
An unconverted man is of the world though he may live like a hermit, and a truly converted man is not of the world, though he be surrounded by the crowds of the city.
It is what is within a man that determines whether or not he is defiled. Mark 7:21-24 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness; All these evil things come from within, and defile the man.
The only way to keep “unspotted from the world” (James 1:27), is to have Christ within. Without that there can be no pure religion." E.J. Waggoner
