The Holy Spirit and the Bible

I closed my last post with a question.  Would the Holy Spirit lead someone to do anything contrary to the written word of God?  The written word of God is the Holy Bible and it was written under the supervision of the Holy Spirit.  Based on the two passages below, the answer to my question must be no.  The Holy Spirit would never lead a believer to do anything inconsistent with the written word of God for the simple reason He authored it.

2 Peter 1: 20-21 “knowing this first, that no prophecy of Scripture is of any private interpretation, for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.”   2 Timothy 3:16-17 “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 complete, thoroughly equipped for every good work.”
 
Of course, if you don’t know what the Bible says it will be difficult to discern what does or does not align with Biblical Truth.  False teachers rely on ignorance of God’s word to gain a following.  The Mystics want you to rely on feelings and circumstance when making moral choices.  However, even with the Disciples the Holy Spirit did not implant new ideas in their heads.  He mainly reminded them of what Jesus Christ said. 
John 14:25-26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you. 
 
In the Gospels we frequently read that the disciples did not understand all that Jesus Christ said to them.  The Kingdom parables are a good example.  In John 12 we also have the example of the Triumphant Entry to Jerusalem on Palm Sunday.  That event was a fulfillment of Old Testament prophecies but the Disciples didn’t realize it until the Holy Spirit brought it back to them later. 
John 12:16 His disciples did not understand these things at first; but when Jesus was glorified, then they remembered that these things were written about Him and that they had done these things to Him. 
It was after the Holy Spirit brought back the memory and made the connections to the Old Testament Scriptures that they came to understand the significance of Palm Sunday. 
 
It is important that every Believer spend time reading their Bible.  It is the only means of measuring the truth.  The Lord knows there are many voices claiming to proclaim the truth of God.  The Holy Spirit had the Apostle John write the following so we could know how to test what we hear. 
1 John 3:24 & 4:1 “Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.  Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world.” 
​The test is does what I’m hearing match up with what the Holy Spirit has already revealed in the Bible.
