“But you wouldn’t believe what he did to me!”
“And he says he is a Christian.”
“It is just way too hard to forgive her for what she did.”
“She didn’t act like she was sorry when she apologized.”
In Luke 17, Jesus implores his followers to work with people of all types with the utmost respect and dignity. To further drive the point home regarding dealing with people and their issues, John Calvin makes a good argument. We have no choice but to forgive people when they repent and ask for forgiveness.
If anyone, therefore, appears before you who is in need of your kind services, you have no reason to refuse him your help.
Suppose he is a stranger; yet the Lord has pressed his own stamp on him and made him as one of your family, and he forbids you to despise your own flesh and blood.
Suppose he is despicable and worthless; yet the Lord has deigned him worthy to be adorned with his own image.
Suppose that you have no obligation toward him for services; yet the Lord has made him as it were his substitute, so that you have obligation for numerous and unforgettable benefits.
Suppose that he is unworthy of your least exertion; but the image of God which recommends him to you deserves that you surrender yourself and all your possessions to him.
If he has deserved no kindness, but just the opposite, because he has maddened you with his injuries and insults, even this is no reaosn why you should not surround him with your affection and show him all sorts of favors.
You may say that he has deserved a very difficult treatment, but what does the Lord command but to forgive all men their offenses and to charge them against himself? (Calvin, GBTCL, 37-38)
