Regarding the faith of Jesus, I count myself among those whom He mentioned here: ""I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me." John 17:20-21. Whatever you wish to call this being-one-in-Us thing is fine with me.
As for the topic of a demi-god..."Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel." Isaiah 7:14. It is my understanding that "Immanuel" means "God with us."
Isaiah 7:14 has absolutely nothing to do with Mary the mother of Jesus, which is what you assume. On the other hand, I tell you that the virgin is Israel. If I pressed you for a quote to document your assertion, you would never be able to produce one. On the other hand, if you pressed me for one to document my assertion, I would give you more than two. Let us assume you have indeed demanded those quotes. Take a look at this:
Psalm 78:67-69 - The Lord rejected Ephraim, the Tabernacle of Joseph and confirmed the Tribe of Judah whom He loved. That's when Israel the Ten Tribes was conquered and removed for good from the Land of Israel by the Assyrians.
Amos 5:2 - Prophet Amos took that divine action in Psalm 78:67-69 as "The VIRGIN Israel has fallen and shall rise no more.
Isaiah 7:14 - A virgin shall conceive and bear a son who shall be called Immanuel.
Isaiah 7:15 - And the son Immanuel shall feed on butter and honey.
Isaiah 7:22 - Butter and honey shall be the food of everyone that is left in the Land. And Judah was left back in the Land after Israel was removed to Assyria, remember?
Isaiah 8:8 - And the king of Assyria invaded throughout Judah, overflowing all over the countryside of thy Land O Immanuel. Thy Land whose land? The Land of Judah. So, Isaiah mentions Judah by name as being Immanuel. Would you be able to be at least half as clear as
I have been about Judah as being Immanuel? I don't think so.
But please don't take this as arrogant excitement for the Truth but a joy to learn something new completely different from what you have been trained to believe.
