Luke 8:38,39 -- Great :Proof that Jesus is God?

Luke 8:38,39 is sometimes referred to as proof that Jesus is the God of Abraham, Isaac and Jacob.

Luke 8:38 - But the man from whom the demons had gone out begged him that he might go with him, but Jesus sent him away, saying,
Luke 8:39 - "Return to your house, and declare what great things God has done for you." He went his way, proclaiming throughout the whole city what great things Jesus had done for him.

According to one author the man from whom Jesus expelled the demons "credited the exorcism to Jesus, although he was told to credit it to God, and he was doing exactly what he was told to do. It seems to me that this man viewed Jesus as God."

Another claims Luke 8:39 is great proof that Jesus is God.

In reality, there is absolutely nothing at all in Luke 8:39, or anywhere else in the Bible, that gives us any reason to imagine and assume that Jesus IS the Supreme Being. Jesus plainly and distinctly identified his God and Father as being the only true Supreme Being, and by saying that the only true Supreme had sent him, Jesus directly denied being the only true Supreme Being. (John 17:1,3) Who sent Jesus? Prophetically, the Messiah says, "Jehovah ... has sent me." (Isaiah 61:1) In Isaiah 61:1, "The Lord Jehovah" is presented as being only one person, not more than one person, and Jehovah anoints and sends another person who is not Himself.

Additionally, the one who was anointed and sent is never once spoken of in the Bible as being a person of Jehovah, the only true God. Nevertheless, Isaiah 61:1 agrees with John 17:1,3, where Jesus identifies his God and Father as being the "only true God". the only true Supreme Being. The "one God" of the Old Testament is the God and Father pf our Lord Jesus (1 Corinthians 8:6; Ephesians 1:3). That one person who spoke through his prophet of Isaiah is identified as one person in Hebrews 1:1,2, and Jesus is distinguished from being that one person.

In Luke 11:20, Jesus stated, "I by the finger of God cast out demons." (World English) Therein, he speaks of "God" as being, not himself, but another, and he speaks of the unipersonal God as being the source of the power by which he casted out demons.

Often in the scriptures we read of various servants of God who performed great acts on behalf of God. Nevertheless, at the same time the scriptures may refer to these acts as being performed by Jehovah himself. Regarding this, let us look at a set of scriptures pertaining to Moses and Jehovah: Exodus 12:51 - It happened the same day,
that Yahweh brought the children of Israel out of the land of Egypt by their hosts. Jehovah alone did lead him [Israel/Jacob - verse 9], There was no foreign god with him. -- Deuteronomy 32:12.

Exodus 15:22: Moses led Israel onward from the Red Sea, and they went out into the wilderness of Shur; and they went three days in the wilderness, and found no water.

Does this mean that since both Moses and Jehovah both delivered the Isralites out of Egypt, that this must mean that Moses is Jehova? No one seriously claims that Moses is Jehovah, yet according to the reasoning of those who wish to scriptures such as Luke 8:38,49 to prove that Jesus is Jehovah, it would seem that these scriptures should definitely prove that Moses is Jehovah. Of course, in reality, Jehovah often takes the credit for what his servants do in his name. Just because one scripture says Jehovah did this or that, and another scripture says that Moses, Gideon, Jesus, or another of God;s servants did the same, does not mean that any of these are Jehovah.

Likewise regarding the Messiah whom Jehovah sent.

So how is it that it can be said that both Moses and Jehovah delivered Israel? Taking the Bible as a whole we learn:

Psalm 77:20: You [Jehovah] led your people like a flock, By the hand of Moses and Aaron.

Hosea 12:13: By a prophet Jehovah brought Israel up out of Egypt, And by a prophet he was preserved.

In this manner it could be said that both Jehovah and Moses brought Israel out of Egypt; it is likewise with the greater Moses, Jesus. -- Deuteronomy 18:15-19.

How well this illustrates also how Jehovah, speaks and performs works by means of his Son, Jesus (John 1:17; 3:34; 5:36; 10:25,32; 14:10; Ephesians 3:9, KJV; Titus 3:6), and delivers the world from sin and death through Jesus, the one like Moses who is also sent by Jehovah.

The unipersonal Most High Jehovah (Luke 1:32,35), having sent His Messiah, does all things through, by means of, Jesus, his son, the one whom He has ordained, appointed and anointed, and our salvation is from the unipersonal God, through the son of the unipersonal God, all to the glorification of the unipersonal God. -- Psalm 2:6; 45:7; Isaiah 61:1; Matthew 11:27; 28:18; Luke 10:22; John 1:17; 3:35; 13:3; 16:15; Acts 4:27; Romans 3:24; 1 Corinthians 8:6; 15:27; 2 Corinthians 5:18; Ephesians 1:3,17,20-22; Philippians 2:11; Colossians 1:3,13,20; Hebrews 1:1,2; 1 Peter 4:11.

Now, did the man from Jesus expelled the demons think that Jesus himself was the God of Abraham, Isaac and Jacob? Those demons recognized Jesus, not as the God of Abraham, Isaac and Jacob, but as the Son of the Most High God. (Luke 8:28) The most logical reasoning is that this man thought that God had performed this miracle through Jesus, not that Jesus himself is the God of Abraham, Isaac and Jacob.

We should definitely note in Luke 8 "God" is always presented as being one person, and not even once as being more than one person.
