I strongly suggest you read this verse in CONTEXT because what I am about to write is out of context but for me muchly applies.

So. What’s the must phrase that I must make my own?

But so what?

Yes. that’s the phrase. But so what?

Let me give it to you from my study notes.
A phrase I need to make my own. 
So what if he or she said this or that or did this or that, or didn’t.
So what!
What matters is ‘is JESUS glorified by the way I RESPOND to it, to him, to her, to all people and all things? ‘

That’s it.  Goodnight.
