The Gospel of Barnabas

God is so rich in mercy that the water of a thousand seas, if so many were to be found, could not quench a spark of the flames of hell, yet a single tear of one who mourns at having offended God quenches the whole of hell, by the great mercy wherewith God succours him. God, therefore, to confound Satan and to display his own bounty, wills to call merit in the presence of his mercy every good work of his faithful servant, and wills him so to speak of his neighbour. But of himself a man must beware of saying: "I have merit"; for he would be condemned.'
