Goodness is to do good to the deserving and love the good and hate the wicked, and not to be eager to inflict punishment or take vengeance, but to be gracious and kindly and forgiving.
Learning to forgive is much more useful than merely picking up a stone and throwing it at the object of one's anger, the more so when the provocation is extreme. For it is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.
I can forgive even that wrong of wrongs,
Those undreamt accidents that have made me
Seeing that Fame has perished this long while,
Being but a part of ancient ceremony
Notorious, till all my priceless things
Are but a post the passing dogs defile.
That your enemies have been created is God's doing; that they hate you and wish to ruin you is their own doing. What should you say about them in your mind? "Lord be merciful to them, forgive them their sins, put the fear of God in them, change them!" You are loving in them not what they are, but what you would have them to become.
That you were once unkind befriends me now, And for that sorrow, which I then did feel, Needs must I under my transgression bow, Unless my nerves were brass or hammered steel.
