Semi, I'm not going to argue your point for yes there are many diverse interpretations and teachings depending upon what denomination you choose to worship with/in. See thought that is a function of humanity and being human for humanity is imperfect. That is also why God decided to and gave His Holy Spirit to those who accepted Christ and are Saved. God's Holy Spirit is the very one that brings peace and understanding unto those Christians.
That doesn't mean that every Christian will be responsive to and listen to His Holy Spirit either but if they are then God will reveal unto the Christian His truth and minister unto them from His scriptures.
John 14:15-17 (CEV) 15 Jesus said to his disciples: If you love me, you will do as I command. 16 Then I will ask the Father to send you the Holy Spirit who will help you and always be with you. 17 The Spirit will show you what is true. The people of this world cannot accept the Spirit, because they don't see or know him. But you know the Spirit, who is with you and will keep on living in you.
Mortal, imperfect, mankind will always disappoint you and everyone else, man/woman is not perfect or sufficient which is why God arranged for His Holy Spirit to be with us and alongside us and literally dwelling in us along with our own inner spirit. God's Holy Spirit can't be seen on any MRI, X-Ray or any other way and cannot be seen but to the individual Christian God's Holy Spirit is EVIDENCE, PROOF, that God is who He says He is and that our Salvation is legit. The scriptures are filled with ministries of the Holy Spirit and that Holy Spirit is the explanation for how the Hatred in a person, how the violence in a life, or how a person's life can be totally transformed and changed in the blink of an eye. Finding Christ, Discovering Christ can do that for anyone.
There are countless numbers of Christians with the SAME testimony about how their lives were filled with grief, anger, contempt, malice, an unforgiving spirit, hatred, you name it and when they met Christ and accepted Christ all that changed in a moment in time and the Peace of God changed their heart into Love. Remember the fruits of the Spirit
Galatians 5:22-23 (CEV)
22 God's Spirit makes us loving, happy, peaceful, patient, kind, good, faithful, 23 gentle, and
self-controlled. There is no law against behaving in any of these ways.
The unsaved, non-Christians seek proof of God, Seek Proof and evidence yet that will never come but for those who acted upon faith, received Christ Message and believed upon Him and accepted God's gift then they received all the proof and evidence that is ever necessary.
One last comment .... don't know if you saw the true story movie about the prisoner of War who survived the Japanese internment camps from World War II. I heard his personal testimony about how after his release all he wanted to do was to return to Japan and Kill those responsible for the torment and punishment he received while a prisoner of War. He was filled with hatred and sought vengeance and was tormented with horrific dreams and desires to seek revenge. He was alcoholic and at the point of losing everything when he went to a Billy Graham crusade at which God reached out to him and he was Saved. He testified that from that moment, that instant, he knew God was upon him and immediately all of his hatred disappeared and love filled his heart and mind and life.
He did return to Japan only to find those who imprisoned him, tortured him to introduce them unto Christ Love, which he did. YES man distorts God's word and argues against each other and Christians do things that are very unchristian at times but God is true to His Word and Promise and changes lives from the inside out, instantly, which is why we should always seek out Christ/God and not rely upon mankind for mankind will always fail.
