After having met a man that had been healed on the Sabbath the Jews made it clear to him that they were not pleased by what Christ had done for him
John 5:10 NIV
and so the Jewish leaders said to the man who had been healed, “It is the Sabbath; the law forbids you to carry your mat.”
Later on the healed man meets Christ in the temple and straight away goes out to the Jews to identify Christ to his accusers
John 5:15
The man went away and told the Jewish leaders that it was Jesus who had made him well.
Having heard the accusations of the Jews which probably carried a death sentence the man finds it neccessary to identify Christ to his accusers
In another similar incident in John 9 the healed man goes out of his way to defend Christ from his accusers
John 9:17 NIV
Then they turned again to the blind man, “What have you to say about him? It was your eyes he opened.”The man replied, “He is a prophet.”
John 9:24-25 NIV
A second time they summoned the man who had been blind. “Give glory to God by telling the truth,” they said. “We know this man is a sinner.”25 He replied, “Whether he is a sinner or not, I don’t know. One thing I do know. I was blind but now I see!”
John 9:30-33 MIV
The man answered, “Now that is remarkable! You don’t know where he comes from, yet he opened my eyes. 31 We know that God does not listen to sinners. He listens to the godly person who does his will. 32 Nobody has ever heard of opening the eyes of a man born blind. 33 If this man were not from God, he could do nothing.”
Unlike the healed man in John 9 the lame man somehow doesn't seem to defend his healer as much as the other one.
Was the lame man trying to placate the Jews?
