John Lewis said this quote

Suffering, though, can be nothing more than a sad and sorry thing without the presence on the part of the sufferer of a graceful heart, an accepting and open heart, a heart that holds no malice toward the inflictors of his or suffering This is a difficult concept to understand, and it is even more difficult to internalize, but it has everything to do with the way of nonviolence. We are talking about love here....This is a broader, deeper, more all-encompassing love. It is a love that acepts and embraces the hateful and the hurtful. It is a love that recognizes the spark of the divine in each of us, even in those who would raise their hand against us, those we might call our enemy.
