John 8:24

24I told you that when you die, God will not have forgiven you. You must believe that “I am who I am.” 8:24 The Jews used ‘I am’ as the name of the Lord God, Yahweh, which means ‘I am who I am’. Jesus said, ‘I am’ to show that he is God. See also verse 28 and verse 58.If not, you will die and God will certainly not have forgiven you.’
