The "He" in Y'shayahu / Isaiah 43:11 is G-d, not Jesus.
G-d alone is our savior.
Funny that missionaries overlook the ONLY as it applies to G-d and state that the savior is Jesus!
"And now, so said the L-rd, your Creator, O Jacob, and the One Who formed you, O Israel, "Do not fear, for I have redeemed you, and I called by your name, you are Mine. . . "You are My witnesses," says the L-rd, "and My servant whom I chose," in order that you know and believe Me, and understand that I am He; before Me no god was formed and after Me none shall be. I, I am the L-rd, and besides Me there is no Savior." Y'shayahu / Isaiah 43:1 - 11.
G-d, through the prophet Isaiah, is saying that Israel (the Jewish people) are His servant, His witnesses. . . He claims us as His and states that there is no other god but He (including Jesus).
How can we know without a doubt that G-d is speaking to and about the Jewish people?
Read the chapter.
"So said the L-rd, your Redeemer, the Holy One of Israel, "Because of you, I sent [you] to Babylon, and I lowered, them all with oars, and Chaldees in the ships of their rejoicing." Y'shayahu / Isaiah 43:14.
The Jewish people were exiled to Babylon. An early paraphrased translation of Isaiah (Targum Yonaton) has "Because of your sins I exiled you to Babylon."
The prophecy refers to the nation as a whole.) G-d is the Savior of Israel, the Jewish people. He alone is our savior.
I, I am the L-rd, and besides Me there is no Savior." Y'shayahu / Isaiah 43:11.
The Jewish bible tells us that we are not to pray to any "god" our fathers did not know (at Sinai). This is the absolute death knell to the missionary claim that Jesus IS G-d. If we did not "know" Jesus at Sinai he is a false god. Read D’varim 11 and D’varim 13 (Deuteronomy):
". . . .the curse, if you. . .turn away from the way I command you this day, to follow other gods, WHICH YOU DID NOT KNOW."
D'varim / Deuteronomy 11: 28
"[This is what you must do] if your blood brother, your son, your daughter, your bosom wife, or your closest friend secretly tries to act as a missionary among you, and says, 'Let us go worship a new god. LET US HAVE A SPIRITUAL EXPERIENCE PREVIOUSLY UNKNOWN BY YOU OR YOUR FATHER.' 13:8 [He may be enticing you with] the gods of the nations around you, far or near, or those that are found at one end of the world or another. 13:9 Do not agree with him, and do not listen to him." D'varim / Deuteronomy 13:7
Acts 4:12 may say "And there is salvation in no one else; for there is no other name under heaven that has been given among people by which we must be saved [for G-d has provided the world no alternative for salvation]." but G-d and the T'nach prove this is a lie.
The very passage the list maker presents as a prophecy about Jesus (which is really about G-d alone) proves that Acts 4:12 is a lie.
I, I am the L-rd, and besides Me there is no Savior." Y'shayahu / Isaiah 43:1 - 11.
Many Christians are taught that only Jesus can save their souls. They believe that Jesus had to die to save them. In this chapter G-d disagrees saying "I, yea I erase your transgressions for My sake, and your sins I will not remember." Y'shayahu / Isaiah 43:25.
No human sacrifice of Jesus.
G-d, G-d alone can erase sins and it does not require Jesus to do it.
In D'varim / Deuteronomy 33:29 Moses said we are “a nation that has been saved by HaShem” and Y'shayahu / Isaiah 45:17 says the Jewish nation “has been saved by HaShem”, adding that “this is an eternal salvation”). Note that, in both verses, the words used were “has been saved” or "continually being saved."
So we don't NEED Jesus to save us -- G-d has saved / is saving us continually, B"H!
