In the Bible it says, there is none other name under heaven given among men, the only Savior is Jesus Christ, the same yesterday, and to day, and for ever. But today why do you believe in Almighty God?

Bible Reference:

“Him that overcomes will I make a pillar in the temple of my God, and he shall go no more out: and I will write on him the name of my God, and the name of the city of my God, which is new Jerusalem, which comes down out of heaven from my God: and I will write on him my new name” (Rev 3:12).

The Answer from God’s Word:

God’s wisdom, God’s wondrousness, God’s righteousness, and God’s majesty shall never change. His essence and what He has and is shall never change. As for His work, however, it is always progressing in a forward direction, always going deeper, for He is always new and never old.

There are those who say that God is immutable. That is correct, but it refers to the immutability of God’s disposition and His substance. Changes in His name and work do not prove that His substance has altered; in other words, God will always be God, and this will never change.

“Jehovah” is the name that I took during My work in Israel, and it means the God of the Israelites (God’s chosen people) who can take pity on man, curse man, and guide the life of man. It means the God who possesses great power and is full of wisdom. “Jesus” is Emmanuel, and it means the sin offering that is full of love, full of compassion, and redeems man. He did the work of the Age of Grace, and represents the Age of Grace, and can only represent one part of the management plan. That is to say, only Jehovah is the God of the chosen people of Israel, the God of Abraham, the God of Isaac, the God of Jacob, the God of Moses, and the God of all the people of Israel. And so in the current age, all the Israelites apart from the tribe of Judah worship Jehovah. They make sacrifices to Him on the altar, and serve Him wearing priests’ robes in the temple. What they hope for is the reappearance of Jehovah. Only Jesus is the Redeemer of mankind. He is the sin offering that redeemed mankind from sin. Which is to say, the name of Jesus came from the Age of Grace, and existed because of the work of redemption in the Age of Grace. The name of Jesus existed to allow the people of the Age of Grace to be reborn and saved, and is a particular name for the redemption of the whole of mankind. And so the name Jesus represents the work of redemption, and denotes the Age of Grace. The name Jehovah is a particular name for the people of Israel who lived under the law. In each age and each stage of work, My name is not baseless, but holds representative significance: Each name represents one age. “Jehovah” represents the Age of Law, and is the honorific for the God worshiped by the people of Israel. “Jesus” represents the Age of Grace, and is the name of the God of all those who were redeemed during the Age of Grace. If man still longs for the arrival of Jesus the Savior during the last days, and still expects Him to arrive in the image He bore in Judea, then the entire six-thousand-year management plan would stop in the Age of Redemption, and would be incapable of progressing any further. The last days, furthermore, would never arrive, and the age would never be brought to an end. That is because Jesus the Savior is only for the redemption and salvation of mankind. I took the name of Jesus for the sake of all the sinners in the Age of Grace, and it is not the name by which I shall bring the whole of mankind to an end. Although Jehovah, Jesus, and the Messiah all represent My Spirit, these names only denote the different ages in My management plan, and do not represent Me in My entirety. The names by which people on earth call Me cannot articulate My entire disposition and all that I am. They are merely different names by which I am called during different ages. And so, when the final age—the age of the last days—arrives, My name shall change again. I shall not be called Jehovah, or Jesus, much less the Messiah, but shall be called the powerful Almighty God Himself, and under this name I shall bring the entire age to an end. I was once known as Jehovah. I was also called the Messiah, and people once called Me Jesus the Savior because they loved and respected Me. But today I am not the Jehovah or Jesus that people knew in times past—I am the God who has returned in the last days, the God who shall bring the age to an end. I am the God Himself that rises up at the ends of the earth, replete with My entire disposition, and full of authority, honor and glory. People have never engaged with Me, have never known Me, and have always been ignorant of My disposition. From the creation of the world until today, not one person has seen Me. This is the God who appears to man during the last days but is hidden among man. He resides among man, true and real, like the burning sun and the flaming fire, filled with power and brimming with authority. There is not a single person or thing that shall not be judged by My words, and not a single person or thing that shall not be purified through the burning of fire. Eventually, all nations shall be blessed because of My words, and also smashed to pieces because of My words. In this way, all people during the last days shall see that I am the Savior returned, I am the Almighty God that conquers all of mankind, and I was once the sin offering for man, but in the last days I also become the flames of the sun that burn all things, as well as the Sun of righteousness that reveals all things. Such is My work of the last days. I took this name and am possessed of this disposition so that all people may see that I am a righteous God, and am the burning sun, and the flaming fire. It is so that all may worship Me, the only true God, and so that they may see My true face: I am not only the God of the Israelites, and am not just the Redeemer—I am the God of all creatures throughout heavens and earth and seas.

Could the name of Jesus—“God with us”—represent God’s disposition in its entirety? Could it fully articulate God? If man says that God can only be called Jesus and may not have any other name because God cannot change His disposition, these words are blasphemy indeed! Do you believe that the name Jesus, God with us, alone can represent God in His entirety? God may be called by many names, but among these many names, there is not one that is able to encapsulate all of God, not one that can fully represent God. And so, God has many names, but these many names cannot fully articulate God’s disposition, for God’s disposition is so rich that it simply exceeds the capacity of man to know Him. There is no way for man, using the language of mankind, to encapsulate God fully. Mankind has but a limited vocabulary with which to encapsulate all that they know of God’s disposition: great, honored, wondrous, unfathomable, supreme, holy, righteous, wise, and so on. Too many words! This limited vocabulary is incapable of describing the little that man has witnessed of God’s disposition. Over time, many others added words that they thought better able to describe the fervor in their hearts: God is too great! God is too holy! God is too lovely! Today, human sayings such as these have reached their peak, yet man is still incapable of clearly expressing himself. And so, for man, God has many names, yet He has no one name, and this is because God’s being is too bountiful, and the language of man too impoverished. One particular word or name does not have the capacity to represent God in His entirety, so do you think His name can be fixed? God is so great and so holy yet you will not permit Him to change His name in each new age? Therefore, in every age in which God personally does His own work, He uses a name that befits the age in order to encapsulate the work that He intends to do. He uses this particular name, one that possesses temporal significance, to represent His disposition in that age. This is God using the language of mankind to express His own disposition. … You should know that God originally had no name. He only took on one, or two, or many names because He had work to do and had to manage mankind. Whatever name He is called by—did He not freely choose it Himself? Would He need you—one of His creatures—to decide it? The name by which God is called is a name that accords with what man is capable of apprehending, with the language of mankind, but this name is not something that man can encompass. You can only say that there is a God in heaven, that He is called God, that He is God Himself with great power, who is too wise, too exalted, too wondrous, too mysterious, and too almighty, and then you can say no more; this little bit is all you can know. This being so, can the mere name of Jesus represent God Himself? When the last days come, even though it is still God who does His work, His name has to change, for it is a different age.

Some say that the name of God does not change, so why then did the name of Jehovah become Jesus? It was prophesied of the coming of the Messiah, so why then did a man by the name of Jesus come? Why did the name of God change? Was not such work carried out long ago? Cannot God this day do a new work? The work of yesterday can be altered, and the work of Jesus can follow on from that of Jehovah. Cannot then the work of Jesus be succeeded by another work? If the name of Jehovah can be changed to Jesus, then cannot the name of Jesus also be changed? This is not unusual, and people think so[a] only due to their simple-mindedness. God will always be God. Regardless of the changes to His work and His name, His disposition and wisdom remain forever unchanged. If you believe that God can only be called by the name of Jesus, then you know too little.
