Now they came to Jericho. As He went out of Jericho with His disciples and a great multitude, blind Bartimaeus, the son of Timaeus, sat by the road begging. And when he heard that it was Jesus of Nazareth, he began to cry out and say, “Jesus, Son of David, have mercy on me!”—Mark 10:46–47
I wonder whether Bartimaeus, a blind man, would have been healed by Jesus if he had simply sat in silence when Jesus walked by. Would Jesus have stopped and turned toward him and touched him? Perhaps. But there were a lot of blind people around during Jesus’ earthly ministry. There were a lot of deaf people. There were a lot of people with leprosy. There were a lot of people with all kinds of physical problems.
But Jesus didn’t heal all of those people, did He? In fact, we usually find in Scripture that Jesus responded to the people who called out to Him. In the case of Bartimaeus, he cried out, and his voice was heard. It probably helped that he screamed. We do not need to scream in our prayers, necessarily, but we do need to be persistent.
