Forgive me for being so contrarian in this thread.
But, the way that I see it, Jehovah and Jesus are not the least bit related. They are polar opposites. In the Old Testament, Jehovah thought it just fine for Joshua and others to slaughter unarmed women and children, to kill infants, and for men to use women for their own sexual indulgements. Yahweh has all of the anthropomorphic atributes of any Roman or Greek God: insecurity, jealousy, fitful outbursts of rage, and arranging elaborate natural disasters to smite his enemies (how can the omnipotent have enemies?) when simply euthenizing them would have sufficed. Yahweh was a fickle, arbitrary, and petty deity who easily got his nose out of joint for the most silly of indescretions. (why would the omnipotent power of the universe care whether or not a man cut off his foreskin, or hair?)
Jesus Christ (at least what is recorded of him) does not even remotely display or express these neurotic personality disorders. I find it curious that there is no Gospel account of Jesus using his Godly power to kill anyone or to strike anyone with leprosy the way that he so easily did in the Old Testament. In the Old Testament, he had no issues with commanding his pet nation to slaughter other nations, yet when he comes to earth; he delivers the "Good Samaritan" parable. I simply see no connection whith Yahweh and Jesus.
Of course, this may be all academic; since I do not believe in the Bible one way or the other.
