Use it as a seed for contemplation. Reflect on it throughout the day. See your life through the lens of this passage. When you forgive, you reclaim your power to choose. It doesn't matter whether you feel someone deserves forgiveness, you deserve to be free.
Forgiveness leads to inner peace.
Once you have forgiven, you will laugh more, feel more deeply, become more connected to others and the good feelings that you generate will pave the way to even greater healing.
