Isaiah 7:14 Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel.
Such an amazing promise over 700 yrs before the event of Jesus' coming. Thats a long time to wait. God says He will give them a sign. What sign? A virgin who will bare the Son of God. Meaning, no earthly father. This hasnt happened before nor since. The child will be a Son and you will call Him Immanuel. Meaning God with us. The Word became flesh and dwelt among us. Many mythical gods men invented were somewhat involved among men yet none actually existed. Now, Jesus, God putting on human flesh, actually doing it and making a reality and revelation of Who God is exactly. Putting all gods to rest and exposing their error.
