Is being offensive ever OK?

Is it legitimate to be aggressive in advancing Gods glory, good purposes, and truth to the point of appearing obnoxious? 

Did Christ ever present himself in a way that was offensive? Did Christ ever seem obnoxious to his adversaries? Was he actually ever obnoxious i.e. extremely unpleasant. Apparently so, enough that his opponents regularly sought to have him killed and ultimately did.

Can we always determine substance by form i.e. does one's external actions/behavior/words always give an indication of one's true motive? 

Christ was accused of operating in the power of a demon. Was this actually what motivated him? If you agree with his claim to be the sinless Son of God, obviously not.  

The bottom line? Being offensive in itself is not necessarily wrong or an indication one is doing wrong. In fact, it can mean the exact opposite. Speaking what is true and doing what is right can be very offensive to ¹some. 

We see no indication that Christ ever asked the forgiveness of the self-righteous Pharisees he offended regularly. Though we do see Christ asking the Father to forgive those who crucified him. 

Matthew 5:9-11 

9 “Blessed are the ²peacemakers, for they shall be called sons[a] of God.

10 “Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven.

11 “Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account.

¹it should be noted he was never found offensive by the humble but only by the proud.

²It is also worth pointing out that peacemaking proceeds persecution. If we are persecuted it should not be because we are personally offensive but that our faithfulness in honoring God is offensive i.e. for righteousness sake...
