To this said Ioasaph, "But how, after baptism, shall a man keep himself clear from all sin? For even if there be, as thou sayest, repentance for them that stumble, yet it is attended with toil and trouble, with weeping and mourning; things which, methinks, are not easy for the many to accomplish. But I desired rather to find a way to keep strictly the commandments of God, and not swerve from them, and, after his pardoning of my past misdeeds, never again to provoke that most sweet God and Master." Barlaam answered, "Well said, my lord and king. That also is my desire; but it is hard, nay quite impossible, for a man living with fire not to be blackened with smoke: for it is an uphill task, and one not easy of accomplishment, for a man that is tied to the matters of this life and busied with its cares and troubles, and liveth in riches and luxury, to walk unswervingly in the way of the commandments of the Lord, and to preserve his life pure of these evils. 'For,' saith the Lord, 'no man can serve two masters; for either he will hate the one and love the other; or else he will hold to the one and despise the other. Ye cannot serve God and Mammon.' So also writeth the beloved Evangelist and Divine in his Epistle, thus saying, 'Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof; but he that doeth the will of God abideth for ever.'
