Do you have eyes, and fail to see? Do you have ears, and fail to hear? And do you not remember? -Mark 8:18 NRSV
I cannot begin to perceive the amount of patience Jesus has for us. The disciples did not start out to be selfless, compassionate men of great courage and devotion. They would eventually grow into such people — but not without the exceptional patience of our Lord and the guidance of our great Comforter, the Holy Spirit.
