If you be one whose heart is eagerly set upon this vain world, I beseech you take heed, lest it interpose itself between Christ and your soul, and so cut you off from him forever. O beware, lest the dust of the earth, getting into your eyes, so blind you, that you never see the beauty or necessity of Christ… Some general aims, and faint wishes after Christ you may have; but alas! the world has centered your heart, entangled your affections, and will daily find new diversions for them from the great business of life; so that, if the Lord break not this snare, you will never be able to deliver your soul.
