Mormons believe that when you die, if you were good enough in this life, you will ultimately reach the highest of heavens, and you would become a god of your own world. This is called the doctrine of exaltation. I encourage you to click the links within the text below to read more on this.
Monolatry in Mormonism ultimately proves the existence of a transcendent, all powerful God, as seen in the Mormonism Impossible series (Part One, Part Two and Part Three). Because this is philosophically and theologically impossible, it ultimately means that Mormonism is false.
Jehovah’s Witnesses (JWs), on the other hand, worship a single “God,” and many of them would argue that they are monotheistic (belief in only one God), but when pressed about Jesus in light of John 1:1, they have little to say about His nature, other than that He is a “little God.” Their translation of John chapter one, verse one, ends with the idea that Jesus was “A” god. It seems that Jehovah’s Witnesses are thus “henotheists.” Henotheism is the worship of a single, highest god, while not denying the possible existence of other “lower” deities. It seems that this description of henotheism fits the bill nicely. Just because they do not teach that there are many, doesn’t not mean that this is an unqualified description. The problem is that they teach that Jesus is a lesser god.
When asked about this, they will often tell you that Jesus is a “lower-case g God.” But what exactly does this mean? When one shows them Exodus chapter 20:3, they often change the subject or deny any part in polytheism. Changing the subject is an easy way out for a Jehovah’s Witness. It is likely one of their most popular tactics, so be ready for it. When this happens, it seems good to gently, but firmly direct them back to your questions.
Jehovah’s Witnesses teach that Jesus is Michael the
Archangel, and because of such, this means that the JW Jesus is incapable of
doing certain things, such as what we see in the book of Jude, verse 9. Michael
cannot rebuke Satan, but in Matthew 4:10, we can clearly see that Jesus does
rebuke Satan. This is clearly a different Jesus than what the Bible teaches.
The reason for this double-knockout between Mormons and JWs is that they distort the truth about Jesus, to which Paul writes in Galatians 1:6-9:
“I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.”
The question is, will the Mormon Jesus or the JW Jesus be sufficient for salvation? It seems that the above passage of scripture gives us the answer to that. The Mormon Jesus and the JW Jesus are literally different Jesus’s than what the Bible teaches, as well as being different Jesus’s from one another. The thing is, neither of them hold to the doctrine of the Trinity.
In John 10:30, Jesus says, “I and the Father are one.” Then after He said this the Jews who heard Him say this wanted to kill Him! The Old Testament orders Jews to kill those who commit blasphemy. It is a serious sin that God wanted to purge from His people. Also, knowing that this would likely be one’s punishment would encourage people not to do it.
The issue here is that the Bible teaches the doctrine of the Trinity, and that Jesus is a person in the Trinity. God is one, but He exists in three Persons. The Jews saw a man before them who was claiming that He was God.
So since the Mormon Jesus and the JW Jesus does not fit this description, teaching that Jesus is truly God and truly man, these false religions both fall short of eternal life: knowing the one true God, and Jesus Christ whom He has sent.

 If Jesus is not God, then He could not forgive sins (See Hebrews 7:25); If Jesus is not man, then He could not be tempted and could not be the perfect sacrifice (See Hebrews 2:17-18. 4:15-16).
