It is fashionable in religion today to hear that no matter what your belief, we all serve the same god. Some call him Allah, some call him Brahma, Waheguru, Jehovah or Jesus Christ. He’s really just God, and we all worship him.
This is, of course, a lie.
There are others who want to segregate the “angry God of the Old Testament” from the loving God of the New Testament. To do this would again be a lie.
Jesus Christ is Jehovah of the Old Testament. God the Father is also Jehovah of the Old Testament. The scriptural proof of this is undeniable unless the Word of God is not trusted.
This is the one true God who eternally exists as one in three entities.
