Yes, King Solomon's throne is said to be established forever. It doesn't mean someone is God when they have an eternal throne in the Bible.
2 Samuel 7
12And when your days are fulfilled and you rest with your fathers, I will raise up your descendant after you, who will come from your own body, and I will establish his kingdom.
13He will build a house for My Name, and I will establish the throne of his kingdom forever.
14I will be his Father, and he will be My son.
b When he does wrong, I will discipline him with the rod of men and with the blows of the sons of men.
15But My loving devotion will never be removed from him as I removed it from Saul, whom I removed from before you.
16Your house and kingdom will endure forever before Me, and
your throne will be established forever.”
Agreed. Believers and Jesus are both in the image of God. You're getting closer to realizing something important.
