Here's a good faith quote from Martin Luther:
"8. For the nature of faith is that it expects all good from God, and relies only on God. For from this faith man knows God, how he is good and gracious, that by reason of such knowledge his heart becomes so tender and merciful, that he wishes cheerfully to do to every one, as he experiences God has done to him. Therefore he breaks forth with love and serves his neighbor out of his whole heart, with his body and life, with his means and honor, with his soul and spirit, and makes him partaker of all he has, just like God did to him. Therefore he does not look after the healthy, the high, the strong, the rich, the noble, the holy persons, who do not need his care; but he looks after the sick, the weak, the poor, the despised, the sinful people, to whom he can be of benefit, and among whom he can exercise his tender heart, and do to them as God has done to him.
9. But the nature of unbelief is that it does not expect any good from God By which unbelief the heart is blinded so that it neither feels nor knows how good and gracious God is; but as Psalm 14:2 says: he cares not for God, seeks not after him. Out of this blindness follows further that his heart becomes so hard, obdurate and unmerciful that he has no desire to do a kindness to his fellow man; yea, he would rather harm and offend everybody. For as he is insensible to the goodness of God, so he takes no pleasure in doing good to his neighbor. Consequently it follows that he does not look after the sick, poor and despised people, to whom he could and should be helpful and profitable; but he casts his eyes upward and sees only the high, rich and influential, from whom he himself may receive advantage, gain, pleasure and honor.
10. So we see now in the example of the rich man that it is impossible to love, where no faith exists, and impossible to believe, where there is no love; for both will and must be together, so that a believer loves everybody and serves everybody; but an unbeliever at heart is an enemy of everybody and wishes to be served by every person and yet he covers all such horrible, perverted sins with the little show of his hypocritical works as with a sheep’s skin; just as that large bird, the ostrich, which is so stupid that when it sticks its head into a bush, it thinks its entire body is concealed. Yea, here you see that there is nothing slinder and more unmerciful than unbelief. For here the dogs, the most irascible animals, are more merciful to poor Lazarus than this rich man, and they recognize the need of the poor man and lick his sores; while the obdurate, blinded hypocrite is so hard hearted that he does not wish him to have the crumbs that fell from his table."
