Exodus 3:13-15 – https://www.biblegateway.com/passage?search=Exodus%203:13-15&version=ESV
Believer Bible Commentary wrote, Exodus 3:14–22 (BBC): Moses anticipated questions from the children of Israel when he returned to them as the Lord’s spokesman, and he wanted to be able to tell them who sent him. It was at this point that God first revealed Himself as Jehovah, the great I AM. Jehovah (more precisely Yahweh) comes from the Hebrew verb “to be,” hāyāh. This sacred name is known as the tetragrammaton (“four letters”). English Jehovah comes from the Hebrew YHWH, with vowel markings supplied from Elohim and Adonai, other names of God. No one knows for sure the true pronunciation of YHWH because the ancient Hebrew spelling used no actual vowels in its alphabet. However, the pronunciation “Yahweh” is probably correct. The Jews consider YHWH too sacred to utter. The name proclaims God as self-existent, self-sufficient, eternal, and sovereign. The fuller name I AM WHO I AM may mean I AM BECAUSE I AM or I WILL BE THAT I WILL BE.
Jesus clearly indicate the He is God and Jewish leader understood real clear understood Jesus claim as God

Despite Jesus is God who came as a man people in Jesus day or even in this present day So the Jews grumbled about him, because he said, “I am the bread that came down from heaven.” They said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does he trnow say, ‘I have come down from heaven’?”
John 6:41-42 – https://www.biblegateway.com/passage?search=John%206:41-42&version=ESV 
Despite that Jesus is God and man as scriptures clearly spell it out. Yet the Jewish people and the in this present age refuse to believe that is God. This is the bread that came down from heaven, not like the bread the fathers ate, and died. Whoever feeds on this bread will live forever.”

Or This was why the Jews were seeking all the more to kill him, because not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.
John 5:18 – https://www.biblegateway.com/passage?search=John%205:18&version=ESV

C. S Lewis wrote “I am trying here to prevent anyone saying the really foolish thing that people often say about Him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God. That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God, or else a madman or something worse. You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher. He has not left that open to us. He did not intend to.” 
Whether believer he is God or not you can not deny he exist in history . You could put this to organ music it or your work tail off in Church program 
It comes down to believing he is the Son of God who came to redeemed humanity from Eve and Adam curse of sin. 
Than asks David Richard Berkowitz known as Son of Sam, Charles Tex Watson the worst of worst killer they carry the burden of sin when confess their sins the burden was lifted From them 
Or the average rebellious teenager who was brought up in Christian home felt this heavy burden on there shoulder, and when they confess they no longer bore theirs sins one minute they felt like grab the moment your eyes the pretty the Christian songs the Bible and the Church services come alive David Berkowitz wrote, “ I spent a good while on my knees praying to Him. When I got up it felt as if a very heavy burden an invisible chain that had been around me for so many years was suddenly broken. A peace flooded over him. He did not understand what was happening. But in his heart He just knew that my life, somehow, would be different. He slept like a baby.
Or Tex Charles Watson wrote Tex than confess repent, and believed in Christ. There was a peace and ecstatic joy that he never felt before in his life. When he went back to his cell , he looked into the mirror, and he saw a smile on his face that brightened up his cell. According to Tex, he never experience this while on drugs or alcohol. The only experience he felt was unending sadness, no rest, and no pleasure in his life only misery.

Or Lee Strobel   a former  Atheists attempting to prove to his wife God did not exist  wrote, “the cross what we cannot do for ourselves: he has paid the death penalty that we deserve for our rebellion and wrongdoing, so we can become reconciled with God. I didn’t have to struggle and strive to try to do the impossible of making myself worthy. Over and over the Bible says that Jesus offers forgiveness and eternal life as a free gift that cannot be earned (see Rom. 6:23; Eph. 2:8-9; Titus 3:5). It’s called grace- amazing grace, unmerited favor. It’s available to anyone who receives it in a sincere prayer of repentance. Even someone like me. Yes, I had to take a step of faith, as we do in every decision we make in life. But here’s the crucial distinction: I was no longer trying to swim upstream against the strong current of evidence; instead I was choosing to go in the same direction that the torrent of facts was flowing.” “admitting and turning from my wrongdoing, and receiving the gift of forgiveness and eternal life through Jesus. I told him that with his help I wanted to follow him and his ways from here on out..

  “To paraphrase Martin Luther King Jr., I may not yet be the man I should be or the man, with Christ’s help, I someday will be-but thank God I’m not the man I used to be! Maybe that sounds mystical to you; I don’t know. Not so long ago it would have to me. But it’s very real to me now and to those around me. In fact, so radical was the difference in my life that a few months after I became a follower of Jesus, our five-year- old daughter Alison went up to my wife and said, “Mommy, I want God to do for me what he’s done for Daddy.” Here was a little girl who had only known a father who was profane, angry, verbally harsh, and all too often absent. And even though she had never interviewed a scholar, never analyzed the data, never investigated historical evidence, she had seen up close the, influence that Jesus can have on one person’s life. In effect, she was saying, “If this is what God does to a human being that what I want for me.”

John Calvin. wrote, O the place of true rest, a place which I consider not unworthy of the name of inner-chamber, where God is seen, not as if disturbed with anger, or distracted by care, but where his will is proved to be good, and acceptable, and perfect. That vision does not terrify but soothe, does not tranquillizes the senses. Here is proper rest. A tranquil God tranquillizes all things, and to see him at rest, is to be at rest. The great I AM is the only bring true peace to our souls.
