I don't know exactly all the differences between all of the different dispensation adherents but I do know any Christian who does not think all of the Bible needs to be considered for doctrine and for teachings about God and his salvation for them including their resurrection unto their sanctification and fullness of what God is offering everyone, is not only missing the mark but are causing others to do so as well
When you look at the phrase, "Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God"
of mankind, as well what is it about phrase, "but by every word that proceedeth out of the mouth of God" does not mean to you and yours that God is saying you need to live by every Word coming from God as found in His Holy Bible?
I would rather you feel hostility towards me than for you and yours to stay on the same path you are on that obviously is rebellion against the commandments of God, and against His Word given to you for your benefit.
That would be a small price for me to pay in comparison to the rewards you would receive if you make the change before it is to late
Again, no offense intended; none taken.
That said, consider that your response is the same one I related has been my friend's.
2 Timothy 2 asserts that:
16. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17. That the man of God may be perfect, throughly furnished unto all good works.
My own understanding of that from it, and other passages, is that it is asserting that because "All scripture is given by inspiration of God," all of it is therefore "profitable."
Not only "for doctrine," or teaching, but "for reproof," or correction of behavior not in line with the teaching, but also, "for correction" of beliefs and or understandings not in line with the teaching.
In short, that to the extent that that is properly carried out, "all Scripture is...for instruction in righteousness:"
For that is why God gave it to begin with - "That the man of God may be perfect," in other words, "throughly furnished unto all good works."
Case in point as to what I'd meant in my prior post that my friend continues to fail to see due to his insistence on seeing things his way:
Parts of the Epistle to the Romans are Doctrine or Teaching.
Following on that; other aspects of Romans are for reproof of behavior that is not in line with said teaching.
While yet other aspects of Romans are for correction of thinking not in line with the teaching Romans has laid out.
All three - Doctrine; Reproof; and Correction, comprise Instruction in Righteousness.
And it is obvious throughout Romans that some things that had been the case in Time Past as to the issue of how faith before God was to be expressed, are Now no longer the case. Example - Romans 3:
19.
Now we know that what things soever the law saith, it saith
to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
20. Therefore by the deeds of the law there shall no flesh be justified in his sight:
for by the law is the knowledge of sin.
In other words, Now we know that what things soever the law had said to them who were under the law, it did so towards the intent that every mouth may be stopped, and all the world may become guilty before God.
In others words, God was doing some things through
Israel's own instruction in righteousness - the Law - proving that by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Romans 3 continues its instruction in righteousness on these things as follows:
21.
But now the righteousness of God
without the law is manifested, being witnessed by the law and the prophets;
22. Even the righteousness of God which is by faith
of Jesus Christ unto all and upon all them that believe:
for there is no difference:
23.
For all have sinned, and come short of the glory of God;
Obviously, there has been a change in how one is to approach God by faith;
not under the Law, as had been the prior case,
But Now, under Grace.
My understanding of that is that it is a Dispensational Distinction (the core issue in Dispensationalism being the issue of Distinctions in Identities as to who, what, when, where, why, and how, (Luke 12:42, Heb. 3:1-6 being two passages that illustrate this principle).
In this, many will assert being "Biblically based" while failing to be Dispensational in their distinctions - applying things in Scripture that are neither for them, nor about them...to themselves.
Another friend of mine is an Adventist; he has yet to understand that one intent of Israel's "instruction in righteousness" - the Law - had been its making them aware, not only of indwelling sin, but of their inability given that they their needed regeneration was yet future: in a coming Messiah.
This was one aspect of why the Lord basically reprimanded Nicodemus, in John 3; as a teacher of Israel's instruction in righteousness to them, he should have know this, but did not.
My point to you in all this is that; assert what you just have all you want to; the above illustrates what I have to believe you well know - that although "all scripture...is for" you, it is not all to you, nor about you.
