Today we’re looking at the word eternal to see what it means. The Greek word for eternal from this verse is; aioônios. The transliteration for eternal from the Strong’s Concordance is: “perpetual (also used of past time, or past and future as well):—eternal, for ever, everlasting, world (began).”
So today ask your Mormon friend what his understanding is of this word when Milton Hunter and Joseph Smith says that God is eternal, yet he was once a man like us and then became a god himself.
The meaning of the word eternal from the Webster’s 1828 Dictionary as found in the Gospel Link Dictionary; “Without beginning or end of existence. The eternal God is thy refuge. Deuteronomy 33.”
Also see definition of eternal from the 1828 Webster’s link here:
“God Himself was once as we are now…It is the first principle of the Gospel to know for a certainty the character of God, and to know that we may converse with Him as one man converses with another, and that He was once a man like us, yea, that God Himself, the Father of us all, dwelt on an earth, the same as Jesus Christ Himself did.”
