Forgiveness, as explained in the snip, involves continuing to love and show respect to someone, irrespective of their actions, while still setting necessary boundaries. It does not imply tolerating mistreatment but rather maintaining a stance of respect and love towards others. The speaker highlights how the cross symbolizes a radical shift in perspective by demonstrating that worthiness of love is not contingent on actions. Instead, the cross signifies a profound act of love and forgiveness where despite being mistreated, one still chooses to extend love and respect to others.
