Hebrews 6:11-12
8 And that you may understand this, listen to the Parable: “A certain man” (it is said) “went down from Jerusalem to Jericho, and fell among thieves”; and when they had beaten him, they left him by the way-side, having badly bruised him. A certain Levite came, and when he saw him, he passed by; A priest came, and when he saw him, he hastened past; a certain Samaritan came, and bestowed great care upon him. For he “bound up his wounds”, dropped oil on them, set him upon his ass, “brought him to the inn, said to the host, Take care of him”; and (observe his great liberality), “and I,” he says, “will give you whatsoever you shall expend.” Who then is his neighbor? “He,” it is said, “that showed mercy on him. Go then also,” He says, “and do likewise.” And see what a parable He spoke. He said not that a Jew did [so and so] to a Samaritan, but that a Samaritan showed all that liberality. Having then heard these things, let us not care only for “those that are of the household of faith”, and neglect others. So then also thou, if you see any one in affliction, be not curious to enquire further. His being in affliction involves a just claim on your aid. For if when you see an ass choking you raise him up, and dost not curiously enquire whose he is, much more about a man one ought not to be over-curious in enquiring whose he is. He is God's, be he heathen or be he Jew; since even if he is an unbeliever, still he needs help. For if indeed it had been committed to you to enquire and to judge, you would have well said thus, but, as it is, his misfortune does not suffer you to search out these things. For if even about men in good health it is not right to be over-curious, nor to be a busybody in other men's matters, much less about those that are in affliction.
9. But on another view what [shall we say]? Did you see him in prosperity, in high esteem, that you should say that he is wicked and worthless? But if you see him in affliction, do not say that he is wicked. For when a man is in high credit, we fairly say these things; but when he is in calamity, and needs help, it is not right to say that he is wicked. For this is cruelty, inhumanity, and arrogance. Tell me what was ever more iniquitous than the Jews. But nevertheless while God punished them, and that justly, yea, very justly, yet He approved of those who had compassion on them, and those who rejoiced over them He punished. For “they were not grieved,” it is said, “at the affliction of Joseph.”
And again it is said “Redeem [Ransom] those who are ready to be slain: spare not.” (He said not, enquire curiously, and learn who he is; and yet, for the most part, they who are led away to execution are wicked,) for this especially is charity. For he that does good to a friend, does it not altogether for God's sake: but he that [does good] to one unknown, this man acts purely for God's sake. “Do not spare” your money, even if it be necessary to spend all, yet give.
But we, when we see persons in extreme distress, bewailing themselves, suffering things more grievous than ten thousand deaths, and oftentimes unjustly, we [I say] are sparing of our money, and unsparing of our brethren; we are careful of lifeless things, but neglect the living soul. And yet Paul says, “in meekness instruct those that oppose themselves, if perhaps God should give them repentance to the acknowledging of the truth, and they may recover themselves out of the snare of the devil who are taken captive by him, at His will.” “If perhaps,” he says; you see of how great long-suffering the word is full.
Let us also imitate Him, and despair of no one. For the fishermen too, when they have cast many times [suppose it], have not succeeded; but afterwards having cast again, have gained all. So we also expect that you will all at once show to us ripe fruit. For the husbandman too, after he has sown, waits one day or two days, and is a long while in expectation: and all at once he sees the fruits springing up on every side. This we expect will take place in your case also by the grace and lovingkindness of our Lord Jesus Christ, with whom to the Father and also to the Holy Ghost be glory, might, honor, now and for ever and world without end. Amen.
