I no longer play that game.
Good point(s).
I concur that many folks who merely want to "argue" aren't about to be convinced by something that they apparently hold in as little regard as mere Scripture. After all, whether most will admit it or not -- especially to themselves -- it's an Idol that they are worshiping in
Monogamania.
Many of us - having had dozens or even hundreds of such conversations - learn to discern the difference in attitude fairly rapidly. (One side note: I often find individuals, like myself, who have been so "turned off" by the hypocrisy they find in many of what I sometimes call "Caesar's Churches of Abounding Grace" that they find the truth about marriage to be a real revelation. It's Jeremiah 16:19.)
For the Hard-core Idolators, depending very much on the level of
unteachability involved, I tend to ask a question or two as well, generally leading in one particular direction:
Does what God has to say about the issue really matter at all to you?
While there's a lot of "rocky ground" out there, occasionally a seed will take root, and people will be inclined to "search out the Truth" for themselves from Scripture.
That, of course, is at least part of the reason for this website. Most people who take it upon themselves to come here actually want to know His answers, as opposed to reinforcing their own vain "tradition".
