"And they came to Jericho... As he was leaving Jericho with his disciples and a great crowd, Bartimaeus, a blind beggar, the son of Timaeus, was sitting by the roadside... He heard that it was Jesus of Nazareth, and he began to cry out and say, 'Jesus, Son of David, have mercy on me!'
...Many rebuked him, telling him to be silent. ['Shut up!!'] But he cried out all the more, 'So of David, have mercy on me!' And Jesus stopped and said, 'Call him.' And they called the blind man, saying to him, 'Take heart. Get up. He is calling you.'
Throwing off his clock, and springing up to his feet, he came to Jesus..."
Before the time of Christ, Plato had written a book called Timaeus. He was grasping at straws in the dark, hoping, and theologizing on who God is, who He must be. He came up with various ideas incorporating geometry and the world around him. Although, he could not know God by his own power or means, one of his characters in this dialogue did have the right idea:
"All men who partake of even a bit of sound-mindedness always call on God."
Plato knew that he must call out. But, he had been fated to remain blind. Perhaps, he gave into his own understanding of God instead of seeking and finding Him for who He truly is.
Either way, the point is that like Timaeus and the followers, sons of Timaeus, we call out to God, hoping to learn who He is. The difference is, we know that we are heard.
'Take heart. Get up. He is calling you.'
We are answered. Jesus Christ calls out back to us, inviting us to come forward.We throw off our cloaks and the worries of this world and rush towards His voice. We are healed.
It is not by our own reason, merit, or strength. But, because of who Christ is and what He has done for us. Although, we may still not understand, He cleanses us and opens our eyes so that we may finally see His face.
"Immediately Bartimaeus recovered his sight and followed Him."
