Charles Spurgeon Commentary John 8:18-21

"I am he that beareth witness of myself, and the Father that sent me beareth witness of me. They said therefore unto him, Where is thy Father? Jesus answered, Ye know neither me, nor my Father: if ye knew me, ye would know my Father also. These words spake he in the treasury, as he taught in the temple: and no man took him; because his hour was not yet come. He said therefore again unto them, I go away, and ye shall seek me, and shall die in your sin: whither I go, ye cannot come." — John 8:18-21 (ASV)

But the Jews did not believe concerning him, that he had been blind, and received his sight, until they called the parents of him that had received his sight. And they asked them, saying, Is this your son, who you say was born blind? how then does he now see?

His parents answered them and said, We know that this is our son, and that he was born blind: but by what means he now sees, we know not; or who has opened his eyes, we know not: he is of age, ask him: he shall speak for himself.

And so he did. He was one of those people who can speak for themselves; and it is greatly to be desired that many more of those who have been cured by Christ could do the same. He was a conscientious man, who, without fear of offending or any desire to curry favor, spoke out honestly what he knew—nothing more.
