Selfishness kills joy because it has unreasonable demands that change instantly. God-centeredness brings joy because He is the unchanging anchor of true goodness and glory.
Very often people are afraid to forgive because they assume that if they forgive, injustice will triumph. Yet the counterintuitive wisdom of Christ reveals that the very opposite is true. It is forgiveness alone that has the capacity to break the chains of injustice and give us the possibility of a new future — a future unchained from the past and free of bitterness.
