1 John 3:17

But thou wilt say to me, And by what am I to know it? For to what it is perfected, we have heard; whence it begins, let us hear. He goes on to say: "But whoso hath this world's good, and seeth his brother have hunger, and shutteth up his bowels of compassion from him, how can the love of God dwell in him?" Lo, whence charity begins withal! If thou art not yet equal to the dying for thy brother, be thou even now equal to the giving of thy means to thy brother. Even now let charity smite thy bowels, that not of vainglory thou shouldest do it, but of the innermost marrow of mercy; that thou consider him, now in want. For if thy superfluities thou canst not give to thy brother, canst thou lay down thy life for thy brother? There lies thy money in thy bosom, which thieves may take from thee; and though thieves do not take it, by dying thou wilt leave it, even if it leave not thee while living: what wilt thou do with it? Thy brother hungers, he is in necessity: be-like he is in suspense, is distressed by his creditor: he is thy brother, alike ye are bought, one is the price paid for you, ye are both redeemed by the blood of Christ: see whether thou have mercy, if thou have this world's means.

Perchance thou sayest, "What concerns it me? Am I to give my money, that he may not suffer trouble?" If this be the answer thy heart makes to thee, the love of the Father abideth not in thee. If the love of the Father abide not in thee, thou art not born of God. How boastest thou to be a Christian? Thou hast the name, and hast not the deeds. But if the work shall follow the name, let any call thee pagan, show thou by deeds that thou art a Christian. For if by deeds thou dost not show thyself a Christian, all men may call thee a Christian yet; what doth the name profit thee where the thing is not forthcoming?
