2 The rich man “went away sorrowful;” and the Lord said, “How hardly shall he that has riches enter into the kingdom of heaven!” And by putting forth a comparison He showed the difficulty to be such that it was absolutely impossible. For every impossible thing is difficult; but not every difficult thing is impossible. As to how difficult it is, take heed to the comparison; “Verily I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.” A camel to go through the eye of a needle! If He had said a gnat, it would be impossible. And then when His disciples heard it, they were grieved and said, “If this be so, who then can be saved?” What rich man? Give ear then to Christ, you poor, I am speaking to the people of God. You are more of you poor than rich, do ye then at least receive what I say, yet give heed. Whosoever of you boast of your poverty, beware of pride, lest the humble rich surpass you; beware of impiety, lest the pious rich surpass you; beware of drunkenness, lest the sober rich surpass you. Do not glory of your poverty, if they must not glory of their riches.
