Closely related to the above is the fact that salvation as the result of calling upon the name of the LORD (Jehovah) is equally predicated of Jehovah in the Old Testament as of Christ in the New. Note the parallel:
“Be glad then, ye children of Zion, and rejoice in the LORD [Jehovah] your God....I am the LORD [Jehovah] your God, and none else....And it shall come to pass that whosoever shall call on the name of the LORD [Jehovah] shall be delivered [saved]” (Joel 2:23-32).
“Christ is the end of the law for righteousness to everyone that believeth....For whosoever shall call upon the name of the Lord shall be saved” (Rom. 10:4,13).
“It is as Jehovah that God became the Saviour of Israel, and as Jehovah He saves the world. And this is the truth embodied in the name Jesus, which is, literally, Jehovah-Saviour.”
How simple to faith is the identity of Jehovah in the Old Testament with Jesus in the New.
