so how do you understand Isaiah 43:10?
Isaiah 43
10 Ye are my witnesses, saith the Lord,
and my servant whom I have chosen:
that ye may know and believe me,
and understand that I am he:
before me there was no God formed,
neither shall there be after me.
11 I, even I, am the Lord;
and beside me there is no saviour.
Isaiah 44
6 Thus saith the Lord the King of Israel,
and his redeemer the Lord of hosts;
I am the first, and I am the last;
and beside me there is no God.
8b ye are even my witnesses.
Is there a God beside me?
yea, there is no God; I know not any.
Isaiah 45
5 I am the Lord, and there is none else,
there is no God beside me:
I girded thee, though thou hast not known me:
6 that they may know from the rising of the sun, and from the west,
that there is none beside me.
I am the Lord, and there is none else.
19d I declare things that are right.
20 Assemble yourselves and come;
draw near together, ye that are escaped of the nations:
they have no knowledge that set up the wood of their graven image,
and pray unto a god that cannot save.
21 Tell ye, and bring them near;
yea, let them take counsel together:
who hath declared this from ancient time?
who hath told it from that time?
have not I the Lord?
and there is no God else beside me;
a just God and a Saviour;
there is none beside me.
22 Look unto me, and be ye saved, all the ends of the earth:
for I am God,
and there is none else.
23 I have sworn by myself,
the word is gone out of my mouth in righteousness, and shall not return,
That unto me every knee shall bow,
every tongue shall swear.
Isaiah 46
5 To whom will ye liken me, and make me equal,
and compare me, that we may be like?
6 They lavish gold out of the bag,
and weigh silver in the balance,
and hire a goldsmith; and he maketh it a god:
they fall down, yea, they worship.
7 They bear him upon the shoulder,
they carry him, and set him in his place, and he standeth;
from his place shall he not remove:
yea, one shall cry unto him, yet can he not answer,
nor save him out of his trouble.
8 Remember this, and shew yourselves men:
bring it again to mind, O ye transgressors.
9 Remember the former things of old:
for I am God, and there is none else;
I am God, and there is none like me,
10 declaring the end from the beginning,
and from ancient times the things that are not yet done,
saying, My counsel shall stand, and I will do all my pleasure.
The Holy Bible declares the Father is God, the Son is God, and the Holy Spirit is God.
There is one God, in three Persons. Not two gods, not three gods. That would be polytheism.
