The Blind Beggar.

"Then they came to Jericho. And as He was leaving Jericho with His disciples and a great crowd, Bartimaeus, a blind beggar, a son of Timaeus, was sitting by the roadside. And when he heard that it was Jesus of Nazareth, he began to shout, saying, Jesus, Son of David, have pity and mercy on me [now]! And many severely censured and reproved him, telling him to keep still, but he kept on shouting out all the more, You Son of David, have pity and mercy on me [now] And Jesus stopped and said, Call him. And they called the blind man, telling him, Take courage! Get up! He is calling you. And throwing off his outer garment, he leaped up and came to Jesus. And Jesus said to him, What do you want Me to do for you? And the blind man said to Him, Master, let me receive my sight. And Jesus said to him, Go your way; your faith has healed you. And at once he received his sight and accompanied Jesus on the road." Mark 10:46-52

The blind beggar shouted for Jesus and made himself known.

He shouted even after everyone told him to be quiet, and louder even.

He screamed for mercy.

And Jesus stopped. He had stopped the very feet of Jesus from passing him.

Jesus called him. "Take courage! Get up!"

Jesus asked him what he wanted and he asked for his sight.

By the blind beggar's faith, Jesus gave him what he'd asked for.

It seems like A + B = C here. It doesn't, A + B rarely = C with God. But at least there's some sort coherence.
