You talk about the “worldview” or one’s philosophy or theology in life. Suppose I forgive but cannot reconcile with the one who hurt me. Might this lack of reconciliation keep me bitter, keep me mistrustful, and actually not alter my worldview to a more positive state once I forgive?
Forgiving can help us to see the special, unique, and irreplaceable character of each person, not just toward the one you are forgiving. When this happens, your trust can increase, not toward the one who hurt you and who remains unrepentant, but now toward more people in general. As you forgive, you realize that all people are capable of love, even though some do not necessarily express it. Some will choose not to love, in which case your trust remains low toward them, but you also begin to realize that other people, who have the capacity to love, do want to grow in this moral virtue. It is in this realization by the forgiver that the worldview can become more positive as trust, toward some, is realistically enhanced.
