We are so sensitive, defensive, and aggressive about asserting that we are right and everyone else is wrong.
Jesus never demonstrated any of that sort of insecurity. He just put it all out there and people could see the truth if they would. When challenged about his authority, he did not waste time arguing it. He knew where his authority came from. That was a fairly important issue for any rabbi.
Rabbis were and are, first, students of some master rabbi and derived authority from that person's credibility.
Jesus knew that his credibility came from His Father. If the naysayers could not see that, he was not going to waste time building a platform for himself with them.
Here is truth. That was his posture. Take it or leave it. Many heard and took it, applied it to their lives, and discovered the authority of his words and deeds through the very witness of of the Spirit.
If you have something from God to share from his Word, share it, but don't get sensitive, defensive, and aggressive about asserting how right you are. If it lands on the right heart, God himself will validate the credibility of his Word.
" One day, as Jesus was teaching the people in the temple and preaching the gospel, the chief priests and the scribes with the elders came up and said to him, “Tell us by what authority you do these things, or who it is that gave you this authority.” He answered them, “I also will ask you a question. Now tell me, was the baptism of John from heaven or from man?” And they discussed it with one another, saying, “If we say, ‘From heaven,’ he will say, ‘Why did you not believe him?’ But if we say, ‘From man,’ all the people will stone us to death, for they are convinced that John was a prophet.” So they answered that they did not know where it came from. And Jesus said to them, “Neither will I tell you by what authority I do these things.” "
