NOTES for Isa 7:1-25
Enemies are approaching Jerusalem, yet the prophet Isaiah promises salvation to King Ahaz and the people. This promise will be confirmed by a wondrous sign: the Virgin will conceive in her womb and bear a Son whose name is "God with us."
Seven centuries later the evangelist will apply this prophecy to the birth of the Savior of Israel, in whom God Himself will visit His people. Thus the news of the coming Messiah becomes salvation for God's people - Christ saves those who believe in Him even seven hundred years before His birth.
