Forgive and be forgiven, hold bound and be held bound. From the depth of Jesus’ humanity, He knows forgiveness is complicated and calls his disciples to this very high standard. Forgiveness is hard when we are sinned against and broken by the hurt.
This story is God’s way of reminding us that He doesn’t want to see those qualities in us either. He doesn’t like it when we are close-minded and dismissive of others. He doesn’t appreciate it when we are sharp-tongued or short-tempered.
