Does the Bible say to question everything?

In this thread, Lord Ashtar says (post #10),

and I’m just curious where exactly it says that and what the exact phrasing is, so that I can perhaps use it in an argument if the opportunity arises. I’m not looking for a debate on what it really means, or whether the Bible is indeed the word of God or not, etc. I’m just looking for facts. Thank you in advance.

Well, there’s 1 John 4:1, which says:

Also Matthew 7:15-20:

“Fruits” in this case means their actions and the results of those actions.

Well, why not just ask Lord Ashtar?

Well, that’s what I had intended to do by asking in the thread itself. But then the thread went in several directions and I got the sense nobody would get to my question. Since it was kinda off-topic anyway, I decided to bring it here. But I’ll ask him anyway to see if he knows of any other passages that ricksummon missed.

Well, the Bible definitely doesn’t say to test everything:

(See also Exodus 17:1-7, and Matthew 4:7 and Luke 4:12.)

I seriously had no idea the NIV was written by slaves.

Gee, the OP made me realize how long it’s been since I’d seen the expression “RTFM!”

Also 1Th 5:21 - “Test all things; hold fast what is good.” (KNJV)

IIRC we are authorized to test everything, but may not temp (God). In some cases there is a fine line between the 2.

(Operating from memory here…) In The Song of Solomon we find…
"Test all things, keep those that prove true.’

Sorry it took so long, but I just got TJdude825’s email. My email service has been acting funny as of late.

The verse I was referring to was 1 Thesalonians 5:21. To take it in context:
