Many people mess up every new day with what happened yesterday. They insist on bringing into today the failures of yesterday, and in so doing pollute a potentially wonderful day. When bitterness, resentment, and revenge are allowed to live in the human heart, words of affirmation will be impossible to speak.
Unforgiveness
J. R. R. Tolkien
It is useless to meet revenge with revenge; it will heal nothing.
Warren Wiersbe
The most miserable prison in the world is the prison we make for ourselves when we refuse to show mercy.
Jason Vallotton
The day that Jesus was crushed for our sins, He revealed the meaning of true justice. Justice was no longer found in revenge, but in forgiveness. Jesus died so that we could be forgiven. Therefore, unforgiveness became an injustice, because a lack of forgiveness nullifies the payment Christ made for us with His own blood.
