Hebrews 10:16-18
6 How? I will tell you, and if you please, I will prove that he who chooses poverty of his own accord is richer even than the king himself. For he indeed needs many [things], and is in anxiety, and fears lest the supplies for the army should fail him; but the other has enough of everything, and fears about nothing, and if he fears, it is not about so great matters. Who then, tell me, is the rich man? He who is daily asking, and earnestly laboring to gather much together, and fears lest at any time he should fall short, or he who gathers nothing together, and is in great abundance and has need of no one? For it is virtue and the fear of God, and not possessions which give confidence. For these even enslave. For it is said, “Gifts and presents blind the eyes of the wise, and like a muzzle on the mouth turn away reproofs.”
Consider how the poor man Peter chastised the rich Ananias. Was not the one rich and the other poor? But behold the one speaking with authority and saying, “Tell me whether ye sold the land for so much”, and the other saying with submission, “Yea, for so much.” And who (you say) will grant to me to be as Peter? It is open to you to be as Peter if you will; cast away what you have. “Disperse, give to the poor”, follow Christ, and you shall be such as he. How? He (you say) wrought miracles. Is it this then, tell me, which made Peter an object of admiration, or the boldness which arose from his manner of life? Do you not hear Christ saying, “Rejoice not because the devils are subject unto you; If you will be perfect [&c].” Hear what Peter says: “Silver and gold have I none, but what I have I give you.” If any man have silver and gold, he has not those other gifts.
Why is it then, you say, that many have neither the one nor the other? Because they are not voluntarily poor: since they who are voluntarily poor have all good things. For although they do not raise up the dead nor the lame, yet, what is greater than all; they have confidence towards God. They will hear in that day that blessed voice, “Come, you blessed of My Father,” (what can be better than this?) “inherit the kingdom prepared for you from the foundation of the world: for I was an hungered and you gave Me meat: I was thirsty and you gave Me drink: I was a stranger and you took Me in: I was naked and you clothed Me: I was sick and in prison and you visited Me. Inherit the kingdom prepared for you from the foundation of the world.” Let us then flee from covetousness, that we may attain to the kingdom [of Heaven]. Let us feed the poor, that we may feed Christ: that we may become fellow-heirs with Him in Christ Jesus our Lord, with whom to the Father together with the Holy Ghost, be glory, power, honor, now and for ever and world without end. Amen.
