Paul speaks of "plausible arguments" in Colossians 2.4, stating that he doesn't want the Colossians church to be led away or deluded by them.
Plausible Arguments, in this case, are those that have enough Truth in them to be dangerous but not enough to actually be True.
"I believe that God is a God of love." But if you use that to justify your sin (as if God isn't just or is apathetic toward sin), then it's a Plausible Argument.
"The Bible is a good guide." But if you use that thinking to dismiss some of it because it's not an authoritative guide, then it's a Plausible Argument.
On and on we could go. But the big thing is this: truth is in Jesus (2.3). If you find Him, you find what you need to know. All the treasures of wisdom and knowledge are in Him.
