How not to engage online if you really want to inform people

I recently had an interaction in a thread on Facebook within a private group. I'm not sure how to describe it—talking past each other, talking in circles, or close-mindedness and unwillingness to interact in good faith. I admit I probably didn't do the best in my interaction (I can tend to be pedantic, especially when people aren't precise enough with their definitions), but the way my interlocutor carried himself is a good example of how not to handle a discussion if you actually want to have your point be considered.

Can believers speak things into existence?

Have you ever heard someone say, while praying, "We're going to call those things that are not as though they were"?

It sounds biblical, and even full of faith, but it's actually not.

The wording used here comes from Romans 4:17, which I am citing here in various translations:

(As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were. (KJV)

As it is written: “I have made you a father of many nations.” He is our father in the sight of God, in whom he believed—the God who gives life to the dead and calls into being things that were not. (NIV)

That is what the Scriptures mean when God told him, “I have made you the father of many nations.” This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing. (NLT)
