Forgiveness is a complex experience that changes an offended person's spiritual feelings, emotions, thoughts, actions, and self-confidence level. I believe learning to forgive the hurts and grudges of our life may be an important step for us to feel more hopeful and spiritually connected and less depressed.
The spiritual journey is one of continually falling on your face, getting up, brushing yourself off, looking sheepishly at God, and taking another step.
