Jonah, Jesus did talk figuratively to convey a message, however, many times it was physical as well.
Was Jonah really swallowed by a whale? Yep, I believe he was.
And, God has many names not just Jehovah. And, I am not negating this name nor anyother.
Jesus came from heaven, not from the dust o the earth (1Corinthians 15:47), and he is Lord of all (Romans 9:5, 10:11-13; he is completely holy and he has authority to judge the world. Therefore Christ is supreme over all creation including the spirit world. Christ deity is paramount to our Christian faith. He is not merely a prophet or a good teacher.
I believe in the trinity of the God of heaven and earth and of the army of angels, Jesus Christ and the Holy Spirit. They are really one deity.
