“”Immanuel means God with Us, or With us is God” Yes and that was Isaiah using prophetic language that was fulfilled in THAT day...not 700 years into the future. The sign was for Ahaz...remember...and G-d WAS certainly with them when the two kings who threatened Israel were killed. Isa 8:10. Take counsel and it will be foiled; speak a word and it will not succeed, for God is with us. See the prophetic connection? It has nothing to do with Jsus.”
Jesus Christ is literally God with us. That is why the sign is that of a virgin (almah, young unmarried maiden) giving birth to Immanuel, el’gibbor (the mighty God), the everlasting Father, the Prince of Peace, as the scriptures as a whole testify.
