The son of Timaeus heard the news and believed that Jesus could heal him. Then Jesus came. He cried, “Have mercy on me” echoing many Psalms (4:1; 6:2; 9:13; 41:4, 10; 51:1; 57:1; 86:3, 16; 119:132; 123:3). University of Montreal Laboratory of Auditory Neuroscience Research1 suggests that a blind person's brain is rewired to use the visual cortex for other senses like sound and touch. By using things like sound reflecting off of objects, many blind people have learned a kind of sonar or echolocation like bats do to “see” things. Because of heightened attention to sounds and touch, blind people often see what “sighted” people cannot. Blind people are careful with their possessions, yet blind Bart threw his cloak aside. Why? He had desire and faith to receive his sight.
