That is a very long question! I do understand it though and believe that most human beings have asked the exact same question at one point in their lives. If I may I will describe my first two sided conversation I had with God.
First of all let me talk a little about science. We know that in the animal world, animals communicate in a telepathical way. It has been proven in research and you can study it more in depth if you wish. There are many forms of communication invisible to us. Bee pherimones, squash a killer bee and for miles around come charging his friends. There are animals, even a paraket that could predict when it's owner was going to have an epileptic siezure. Dogs that can know when thier master is going to have a siezure, even diagnose cancer. Think about radio waves, they blow my mind. So to imagine that the Intelligent Designer of all this could communicate to us in a sometimes invisible way, is not crazy or unscientific.
Most often today Christians will not say they hear an audible voice of God. It is on a telepathic level that has physical actions that confirm the communication. Often a Christian will have strong feelings to move in a particular direction after prayer and or Bible reading seeking Gods will in thier lives. Following Jesus cannot be based on a feeling but also on His written word.
My first two sided conversation happened like this; I was an unbaptized publisher with three children. I had been raised in the WTBTS since childhood. My life up to that point had been spent seeking Jehovah through the WTBTS. I had a closer relationship with the WTBTS than I had with Jehovah. I felt that since I was not yet baptized, not yet making a decent amount of hours out in service, not attending all the meetings..that I was not worthy or aproved.
With this mindset, I ended up in the hospital dieing with massive abdominal peritonitus from a hysterectomy gone very bad. Fevers that would not go down. Unbelievable pain. Paralyzed intestines, I would stop breathing when I fell asleep and force myself to wake up and gasp for breath. The Doctor came in and apologized, there was nothing more he could do. My JW friends came to say thier goodbyes. I was frantic. I was not ready to die! On the 6th day I prayed and begged God for more time. This is the part I think you want to hear. I was visited in the Spirit by Jesus. He came to me, lifted the veil and stayed with me that dark fearful night. He spoke to me in the Spirit, told me I could honor Him, give Him glory, and call on Him. I surrendered my life to Him that night. He already bought and paid for me, but He wanted to hear it from my own heart. The manifestation of that night was confirmned the next morning by a miracle. My fever broke, the machine the GI tube was attached to was malfunctioned and the nurse easily discovered it and hooked me up to the hospital wall aspirator, which then aspirated the contents of my stomache. I was drowning in my own bodily fluids, it was full of unexplained blood and mucous. It took four hours to aspirate. My demeanor also changed drasticaly. I was frightened, now I was at peace. Incredible serene peace. I was lost, now I was found.
When the JW friends came that day hearing I was still alive they were terrified of what they seen and heard. They seen a miracle with their own eyes. My life since then has been beautufil. It has not been easy but I have never been alone. I now have a personal relationship with God through His Awesome devine Son. The proof is evident in my life. I felt His presence, I heard Him that night without words. I did not create this miracle, if so I would be certifiably schitzophrenic which I assure you is not the case. I may be excentric, but very sane.
I have a deep .......peace... now of why bad things happen to good people. I guess it is because my faith is powerful after what I experienced. I can not put into words how I trust that God has a plan for all suffering. I hate it, He hates it too. God is not unable to smash the bad guys, He is allowing it for a time. Death is not a terrible end. God has given me thirteen years since the experience in the hospital. I may not live through this year. If we can put our lives here in true biblical perspective, our time on earth is but a short little test in the eternity of our lives. All our lives have a purpose and God has a plan. I believe that every godly person suffering unto death is now in the presence of God. I believe it because the Bible tells me so.
