The observation and question re various and even conflicting views by those who each claim to be taught or led by the Spirit, is indeed one that must be come to grips with. Here's just a smattering of base thoughts on it....
God will not contradict Himself. That does not mean that persons will not be told different things at different times. That is wholly different that contradiction, as it can happen without any contradition whatsoever.
God is one. One mind. One baptism. One spirit. Etc.. I'm sure that we are familiar with the various scripture verses that state that God does not change, etc..
God is not bi-polar, or multi-polar, or that defies the very definition of God.
The scritpures can be read, memorized, studied, etc., but that does not give spiritual wisdom or insight. Scripture is rife with this truth also. The Pharisees knew the word quite well, but were very blind spiritually. Christ stated this a number of times, and in no uncertain terms! This was also spoken of in the OT, quite often. And Paul even quotes one of those many times from Isaiah. So obviously, reading the word of God can be completely useless to us spiritually. Or it can be rewarding beyond measure. The scriptures state also that it is the Spirit (God) who opens the spiritual eyes. Thus, the obvious conclusion is that without the God opening our spiritual eyes while we read the word of God, we will come to erroneous conclusions. To aver otherwise is to be devoid of even basic understanding and dictionary definitions of words that we use! Spiritual things are NOT a democracy. It is not a majority vote of the citizens. God has His truth. We must have it too, "having been conformed to his truth", the word states. The word also states that when we are one in the God, anything that we don't have agreement one, those periphery things, God will bring us into unity on them. This then begs the obvious question, "why don't we see this happening?" Again, there can be but one answer: we are not all walking in God, but are listening to various voices. Christ stated that those who are born of God, hear His voice, and that they don't hear the voice of others, but do what God's voice tells them. This then demands the conclusion that, just as the apostles wrote in the NT episltes, there are false teachers who lead many astray, teaching doctrines of demons. If they are not teaching the doctrine of God, as evidenced by teaching contrary to God's truth in it, then there aren't any other options for where that doctrine came from! That is a very, very basic of spiritual things: God or Satan. Light or darkness. Clean or unclean. There is no such thing as partial God, or partial Satan, or partial light, etc.. This is why the word states that those new in Christ are yet carnally minded, and that the carnal mind is at enmity with God, so the new in Christ need to remew their mind in Christ Jesus their Lord and Savior. We cannot renew it in Dobson's teachings, Graham's teachings, Colson's teachings, etc.. This is why the scriptures state that those born of God actually have the mind of God. Powerful. But not lived by most, as the proof in the pudding completely reveals. Tragic. We have no need that any man teach us ("do you teach yourselves?"), for we have been given God without measure. That's a fact for those born of God. We are "partakers of the divine nature." That's a fact for those who are actually born of God. "God gives himself without measure". That's a fact for those born of God. Apes give birth to apes. Apples to apples. People to people. God to .....
Well, are you born of God or not? "God is spirit" Christ said. And He said that you must be born of spirit to enter heaven. You MUST be born of God Himself. This is why Christ was the firstborn of many BRETHREN.
Scripture is to be rightly divided, it states. And that is done SOLELY by the Spirit opening our eyes to it. We cannot acquire this on our own, even while seeking the Spirit in it through aides, commentaries, lexicons, etc.. "comparing spiritual with spiritual". That does NOT mean comparing Greek words, Hebrew words, commentaries, etc.. Also, look at 2 Peter 1:20. It sheds no little light on these facts. "knowing this first, that no prophecy of the scripture is of any private interpretation". And everybody seems to stop right there. OK, let's just take that, then. What does "private" mean? It has various meanings. Somebody has duped us into fully and exclusively believing that it means our own, or personal. So let's look at the context, OK?
(2Pe 1:16) For not having followed fables having been cunningly devised, but becoming eyewitnesses of the majesty of Jesus Christ, we made known to you the power and coming of our Lord.
Scripture is not fables, but the word of God. It is the truth. It is spiritual fact. As such, it teaches spiritual and actual facts of events also.
(2Pe 1:17) For He received honor and glory from God the Father, when was borne to Him a voice from the excellent glory, "This is My beloved Son, in whom I am well pleased."
We see that the NT speaks of the fulfillment of the OT. As such, it is claimed to be scritpure, to be spiritual truth and fact, in these two verses.
(2Pe 1:18) And we heard this voice being borne from Heaven, being with Him in the holy mountain.
This speaks volumes, in light of the OT and God speaking to Israel from the mountain, but they stopped up their ears in fear and whatnot, and wanted God to speak to them through their leader(s). But God had told them to harken to His VOICE. And we see the terrible fruit of such a heart state, exampled in the wickedness and sins that God had to punish for 40 years in the wilderness. And they persisted in that state even after entering the promised land. Such is the state of Christendom even today, for they insist on listening to their leaders instead of hearing God directly. And just look at the sinfulness, the wicked statistics of Christendom. Only a complete fool would state that the church is not living in wickedness. Even our secular news is filled with these facts every day regarding Christendom's wickeness that everyone sees, but we are unwilling to admit are ours. Tragic. How great is that blindness.
(2Pe 1:19) We also have a more sure Word of prophecy, to which you do well to take heed, as to a light that shines in a dark place, until the day dawns and the Daystar arises in your hearts,
The scriptural prophecies are even more sure. We are to take heed to them. They are the spiritual light until God's personal light is actually in our hearts. And we saw that it was just previously stated that they were witnesses of thoe prophecies coming to fruition. Thus, the conclusions regarding the previous verses are fully varified yet again by this verse.
(2Pe 1:20) knowing this first, that no prophecy of the Scripture came into being of its own private interpretation.
And that is the foundation for this verse, isn't it! Scripture is not of it's own interpretation, but we are to compare scripture with scripture, with the holy spirit, God Himself, opening our eyes to the spiritual truths hidden therein to all other commers. Without God epening our eyes, we are yet blind and completely off beat in the beliefs that we arrive at when we study the word of God.
And we don't need to know any Greek or Hebrew for this to occur, or the Word would have stated that we need the Spirit to open our eyes in conjunction with linguistic acumen. To require this, is to negate the power of God. We even have the word state that if we add to Christ, we make Him of no account, for obviously, then, Christ wasn't sufficient. If we add to the Spirit, we make Him of no account, for He needs assistance. Bah! Who states that God needs assistance, and yet claims to know God and walk with Him and be taught with Him? Such a one is a fool, speaking things they know nothing of, leading many astray. We have this truth varified in Acts at Pentecost, when God came down on the believers and they spoke the gospel in the native tongues of all the hearers. And they are the ones that spoke Greek naturally, unlike any of us can ever dream of doing, knowing all the cultural nuances, idioms, etc.. But God gave the spiritual truth to the damned in completely different languages. He did NOT have the hearers understand Greek or Hebrew! Those who teach that we need to learn Greek or Hebrew in order to have a better understand of God's word are liars on two counts: spiritiual things are spiritually understood, not linguistically understood; and God is not limited in any way, let alone by linguistics or volume of reading. And they are also false on the other counts, such as "no need that any man teach you", "you have the mind of Christ", "God gives His spirit without measure", etc..
But the setup, the structure of the church fully constrains Christendom to to very opposite of what the scritpures expressly state. This is tragic.
(2Pe 1:21) For prophecy was not borne at any time by the will of man, but holy men of God spoke being borne along by the Holy Spirit.
And this verse is the nail in the coffin of the misbelief so rife in Christendom regarding verse 20.
So we must ask ourselves, as a previous post did: why is it that we have such varied "spirit led" beliefs? It proves the spiritually blind state of Christendom. And if we insist on continuing on in our way, blithely believing that we are the ones exempt from this, we are most blind. "How great is that darkness."
It's enough to make a man weep.
