Oscarr,...... you've made fence laws for yourself in scripture.
The prophet office is no different from the OT one, it's just very, very rare. It comes with a hefty price, and it's the very reason why we don't see any. Everyone wants their McMinistry now.
Also,..prophesiers are not prophets.
I thought carefully about this overnight. What I have concluded is that God has not stopped speaking to us and guiding us by the Holy Spirit within us.
I discovered that a hard and fast compliance with Scripture without the anointing of the indwelling spirit causes a cold religious spirit that can be unyielding and judgmental on those who don't comply with the "instruction manual".
What we need is for the Scripture and the Holy Spirit to work together. When I was not living according to God's standards during my storm and stress years, the Holy Spirit said to me, "You are not living according to God's standards are you?" Now, you won't find that in the text of Scripture, but I knew that was the Holy Spirit speaking to me. I replied, "No, I'm not. What do you want me to do about it?" He said, "Keep talking to me about it and we will work through it to get you back on track". And so I did, and circumstances changed to enable me to put things right and get back on track.
But if I had a voice in my head saying, "Leave your church and go and be a Jehovah's Witness and adopt their doctrines", I would know that it wasn't the Holy Spirit who was telling me that. How do I know the difference? It is because I know the Scriptures and know that the JW church is a cult and their doctrines are false. Also, the Holy Spirit is not going to tell me to go a burgle a house, shoplift, or beat someone up. Why? Because the Holy Spirit is not going to contradict things that God has already shown us in the Scriptures.
The Holy Spirit might give me a word of knowledge that an elder of my church is having an affair with the church secretary. Would that be the Holy Spirit? It might be and then it might not be and if I went and blurted out, "This is what the Lord has shown me..." I might destroy a marriage and divide the church. So what do I do? I ask the Lord for a word of wisdom to know how to approach the elder, and the Holy Spirit might tell me to encourage the elder that faithfulness to his family will result in God's blessing on his family and ministry. That way, I would know if the word of knowledge is from the Holy Spirit or not. If the elder breaks down and confesses his affair, then that would be confirmation that the word of knowledge did come from the Holy Spirit.
Although the content of the word of knowledge did not come from the pages of Scripture, it was in accordance with Scripture because it was wrong for a church elder to have an extra-marital affair with the church secretary.
It is the same with prophecy. The content of a prophecy may not directly echo the text of Scripture, but if it is in accordance with the spirit of Scripture, that it would be something that we know that Jesus would say, then we would know that it would have an impact on the listeners to draw them closer to Christ and strengthen their faith.
The thought that influenced me was that if God had been speaking to His saints from Adam right through to the Apostle John, the last Apostle, has He suddenly gone silent.
Francis Schaeffer wrote a book called, "God is there and He is not silent". This means to me that He has not stopped speaking. Old time prophets spoke and wrote as they were moved by the Holy Spirit. The Apostles spoke and wrote as they were moved by the same Holy Spirit; so why not modern prophets, pastors, and teachers speaking and writing as they are moved by the Holy Spirit?
John Bunyan wrote "Pilgrims Progress" which after several centuries, remains the best selling book outside of the Bible. But apart from Scripture quotes, most of it does not come directly from the pages of the Bible, but he was inspired by the Holy Spirit regardless. The results show it in the number of people converted to Christ while reading the book.
I have had the constant experience of buying a Christian book and had the Holy Spirit speak through almost every page through the wisdom of the author. Even though the book was extra-Biblical, it was not non-Biblical. For me, the book was prophetic, and many modern prophecies come through the books of good Christian authors.
So, when we hear a prophecy, we can evaluate on the terms of whether it is extra-Biblical or non-Biblical. All prophecies given are extra-Biblical because they don't directly quote the Bible, but the questionable ones appear to be non-Biblical, and to be able to discern that one has to know what God has said in the Bible.
I wrote a book about how God speaks to me, and after hearing some teaching by John MacArthur about the absolute priority of the Written Scripture to guide us, I thought that my book might not be true and contained false teaching. But after realising that God can speak extra-Biblically, I felt better about my book, because nothing that the Holy Spirit said to me, shown in the pages of my book, were non-Biblical.
