"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." - Isaiah 43:10 (KJV)
In King Follett Sermon, Joseph Smith teaches that members of the LDS church may too become gods one day:
Eternal Life to Know God and Jesus Christ (King Follett Sermon)
The scriptures say it, and I defy all the learning and wisdom and all the combined powers of earth and hell together to refute it. Here, then, is eternal life—to know the only wise and true God; and you have got to learn how to be gods yourselves, and to be kings and priests to God, the same as all gods have done before you, namely, by going from one small degree to another, and from a small capacity to a great one; from grace to grace, from exaltation to exaltation, until you attain to the resurrection of the dead, and are able to dwell in everlasting burnings, and to sit in glory, as do those who sit enthroned in everlasting power. And I want you to know that God, in the last days, while certain individuals are proclaiming His name, is not trifling with you or me.
Moreover; we are aware that the Church of Latter Day Saints believes that the Godhead (Father Son & Holy Ghost) are three separate gods sharing the same will.
Although the members of the Godhead are distinct beings with distinct roles, they are one in purpose and doctrine. They are perfectly united in bringing to pass Heavenly Father's divine plan of salvation.
Also; Abraham 4 teaches creation was committed by multiple gods.
- And then the Lord said: Let us go down. And they went down at the beginning, and they, that is the Gods, organized and formed the heavens and the earth.
With this in mind; How does the Church of Latter Day Saints interpret Isaiah 43:10? Bonus points if the verse is kept in context.
