V. Our resolutions to cleave to and follow those that are turning to God, and joining themselves to his people, ought to be _fixed_ and _strong_, because of the great difficulty of it. If we will cleave to them, and have their God for our God, and their people for our people, we must mortify and deny all our lusts, and cross every evil appetite and inclination, and forever part with all sin. But our lusts are many and violent. Sin is naturally exceeding dear to us; to part with it is compared to plucking out our right eyes. Men may refrain from wonted ways of sin for a little while, and may deny their lusts in a partial degree, with less difficulty; but 'tis heart-rending work, finally to part with all sin, and to give our dearest lusts a bill of divorce, utterly to send them away. But this we must do, if we would follow those that are truly turning to God. Yea, we must not only forsake sin, but must, in a sense, forsake all the world: Luke xiv. 33, "Whosoever he be of you that forsaketh not all he hath, he cannot be my disciple." That is, he must forsake all in his heart, and must come to a thorough disposition and readiness actually to quit all for God and the glorious spiritual privileges of his people, whenever the case may require it; and that without any prospect of any thing of the like nature, or any worldly thing whatsoever, to make amends for it; and all to go into a strange country, a land that has hitherto been unseen; like Abraham, who being called of God, "went out of his own country, and from his kindred, and from his father's house, for a land that God should show him, not knowing whither he went." Thus it was a hard thing for Ruth to forsake her native country and her father and mother, her kindred and acquaintance, and all the pleasant things she had in the land of Moab, to dwell in the land of Israel, where she never had been. Naomi told her of the difficulties once and again. They were too hard for her sister Orpah; the consideration of them turned her back after she was set out. Her resolution was not firm enough to overcome them. But so firmly resolved was Ruth, that she broke through all; she was steadfast in it, that, let the difficulty be what it would, she would not leave her mother in law. So persons had need to be very firm in their resolution to conquer the difficulties that are in the way of cleaving to them who are indeed turning from sin to God. Our cleaving to them, and having their God for our God and their people for our people, depends on our resolution and choice; and that in two respects.
