I get what you're saying. But no one has addressed my first example.
I assume since this is the Charismatic, Spirit-Filled forum, we can safely assume that we all believe that the Holy Spirit actively speaks to us and leads us. How then does one "line up" such things with scripture? To repeat the example, let's say you're out shopping, and God speaks to you and tells you to minister to the guy in front of you at the checkout lane. How does one "line up" with scripture that specific instruction or "experience"?
Then perhaps the first scripture that would confirm that is
Matt 28:18-20
All power is given unto me in heaven and in earth.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
KJV
Or let's say that you see a person who is struggling financially that you want to help, but God tells you
not to help that individual, because you'd only be enabling their problems.
2 Thess 3:10
For even when we were with you, this we commanded you, that if any would not work , neither should he eat .
KJV
These are the kinds of "instructions" and "training" that you simply will not find in scripture. There is no way to verify what to do in individual circumstances such as these apart from the learning to listen to and heed the voice of God. The answer to "Should I help or shouldn't I?" isn't one found in scripture. The instruction to "Minister to that guy in the blue jacket" isn't found in scripture either.
That's why I said the premise being put forth, that
only scripture is profitable for instruction and teaching is an imbalanced teaching that reduces God to words on a page instead of an ALIVE God that is constantly speaking to us, instructing us, and leading us in all things.
