No one can prove that God does or doesn’t exist, but tough acts of forgiveness are pretty convincing for me. It is so not my strong suit, and I naturally prefer the company of people who hold grudges, as long as they are not held against me. Forgiveness is the hardest work we do. When, against all odds, over time, your heart softens toward truly heinous behavior on the part of parents, children, siblings, and everyone’s exes, you almost have to believe that something not of this earth snuck into your stone-cold heart.
