One time, I remember, going into the Strand, a poor and infirm old man craved his alms. He beholding him with eyes of pity and compassion, put his hands in his pocket, and gave him 6d. Said a divine (that is Dr Jasper Mayne) that stood by - 'Would you have done this, if it had not been Christ's command?' 'Yes,' said he. 'Why?' said the other. 'Because,' said he, 'I was in pain to consider the miserable condition of the old man; and now my alms, giving him some relief, doth also ease me.'
If you haven't done so already, read Leviathan.
