2 Corinthians 8:9
If you meet a sinner, do not turn your back on him, as a Pharisee might, but help him all you can, for Christ helped you all he could. If it should cost you a great deal of trouble to win that soul for Christ, gladly put yourself to that trouble, because Christ took so much trouble to save you.
A good brother said to me, the other day, concerning a certain boy, that he was afraid we should never do much with him because he was of very corrupt origin. I said, “So were you.”
He replied, “I do not quite mean it that way.”
“No,” I said, “but I do mean it that way.”
He or she who is a son or daughter of Adam had a corrupt origin. As we all came from that source, we are all corrupt. Do not ever say of anybody, “That person is too bad for me to do anything with him.” It is the genius of Christianity to select the worst first, and we should never regard any man as utterly hopeless until he is dead. As long as the breath is in his body, even if all the devils from hell were also in him, there is enough power in the Lord Jesus Christ to make the whole troop of them fly, and it is for us to attack those devils in his name. Jesus Christ having saved us, the salvation of other sinners must be possible.
