Continuing in Isaiah we find a description of great suffering, war and blindness under the reign of King Ahaz.  But in the middle of this great time in history some 700 years before the birth of Jesus, we find the great prophecies regarding the Birth of Jesus (Isaiah 7:14) being one says  "...a virgin shall conceive and bear a son and shall call his name Immanuel."  Revelation 19:10 (kjv) "....the testimony of Jesus is the spirit of prophecy."  May we have ears to hear and hearts to receive what the Spirit of God says.
