Anger will eat you alive. As I was reading this morning from Genesis, you could feel the hatred that Esau had for his deceptive brother.
Genesis 27:41 Esau held a grudge against Jacob because of the blessing his father had given him. He said to himself, "The days of mourning for my father are near; then I will kill my brother Jacob." 42 When Rebekah was told what her older son Esau had said, she sent for her younger son Jacob and said to him, "Your brother Esau is consoling himself with the thought of killing you.
Esau is finding comfort in the hope of destroying his brother. How do you forgive someone who has lied and stolen the most important things you have?
