Here is a guest thought from my friend, Josiah Meyer:
Here are some verses which would save some apologists a lot of time and heartache:
Proverbs 23:9 “Do not speak in the hearing of a fool, For he will despise the wisdom of your words.
Prov. 29:9 “When a wise man has a controversy with a foolish man, The foolish man either rages or laughs, and there is no rest.”
Ecc. 7:6 “For as the crackling of thorn bushes under a pot, So is the laughter of the fool; And this too is futility.”
Matthew. 7:6 “Do not give what is holy to dogs, and do not throw your pearls before swine, or they will trample them under their feet, and turn and tear you to pieces.
Some people just have no interest in truth, or at least have no interest at a certain moment, or in a certain context. There is a time and place to just say, “Enough. You’re not listening or trying to understand what I am saying. This conversation is going nowhere, and I think we both have better things to talk about, don’t you? If at some time in the future you are SERIOUSLY interested in my point of view, I am very much willing to return to this conversation!”
