This is Jehovah speaking in the Old Testament.
Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear. (Isa 45:22-23 KJV)
This is Jehovah promised in the Old Testament.
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. (Isa 9:6 KJV)
This is Jehovah in fulfilment of prophesy here on earth.
That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Php 2:10-11 KJV)
I'm happy to believe Jesus is the WORD made flesh. Or to put it simply, "Jesus is God in overalls."
