34. 5. The complete union of the divine nature and the human nature in him was effected by the suffering on the cross, which was his last trial.
Support for this proposition was provided above , in the chapter explaining that the Lord came into the world to subdue the hells and to glorify his human nature, and that the suffering on the cross was the last battle, by which he gained complete victory over the hells and completely glorified his human nature. Since, then, by suffering on the cross the Lord completely glorified his human nature-that is, united it to the divine nature-and thereby made his human nature divine as well, it follows that he is Jehovah and God in respect to both natures.

Jehovah Sabaoth is his name, and your Redeemer, the Holy One of Israel. He will be called the God of the whole earth. (Isaiah 54:5)
 We can see from these passages that the Lord’s divine nature called “the Father” (and here called “Jehovah” and “God”) and his divine human nature called “the Son” (and here “the Redeemer” and “the Savior” as well as “the Maker, ” meaning the Reformer and Regenerator) are one, not two, for it not only says “Jehovah is God” and “the Holy One of Israel is the Redeemer and Savior, ” it also says “Jehovah is the Redeemer and Savior.” Not only that, it even calls Jehovah “the Savior” and says, “there is no Savior other than me.” This clearly shows that the divine nature and the human nature in the Lord are one person and that the human nature is divine as well, since the Redeemer and Savior of the world is no other than the Lord in his divine human nature, which is called “the Son.” Redemption and salvation are properly credited to his human nature, and are called “merit and righteousness, ” since his human nature bore the trials and the suffering on the cross, which means that he accomplished redemption and salvation by means of his human nature.
 Since, then, after the union of his human nature with his inner divine nature, which was like that of soul and body in us, they were no longer two but were one person (according to the teaching of the Christian world), the Lord was Jehovah and God in both respects. This is why some passages speak of “Jehovah” and “the Holy One of Israel the Redeemer and Savior, ” but others say “Jehovah is the Redeemer and Savior, ” as you can see from the citations above.
