“Since you are so ‘reasonable,’ you gladly put up with the unreasonable ones.”
~2 Corinthians 11:19

Was the Apostle Paul being sarcastic when he made this statement?
The context shows that the “unreasonable ones” refers to apostate Christians who were criticizing him in his absence. (2 Cor. 11:3-6,12-15).
Paul put up with a lot to carry out his ministry, including physical persecution and health problems. (2 Cor. 11:24-27;12:7).
But he was especially sensitive to the negative attitudes the Christians in Corinth had towards him.
It hurt him to have to defend his own reputation before his brothers. (2 Cor. 12:11,16)
Today we may come across negative, one-sided information about other Jehovah’s Witnesses.
It would be unwise to “put up” with apostate material that tries to weaken our faith in God’s congregation.
