John Wesley on Luke 18:22

Yet lackest thou one thing - Namely, to love God more than mammon. Our Saviour knew his heart, and presently put him upon a trial which laid it open to the ruler himself. And to cure his love of the world, which could not in him be cured otherwise, Christ commanded him to sell all that he had. But he does not command us to do this; but to use all to the glory of God.
