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.
So you believe that this verse is teaching that the Father is the only true God and since you believe that the Father, Son, and HS are separate and distinct you must also believe that the Son and the HS are false Gods. Is that what you really believe?
