Ahaz was king of Judah. Judah was being attacked by a coalition of nations and Ahaz and Judah were in deep trouble. God sent Isaiah with a message of reassurance, but Ahaz refused to honor God’s request. His refusal to ask for a sign was not faith, it was arrogance. God gave him a sign anyway. A virgin would bear a child and call His name Immanuel (God is with us). This prophecy was fulfilled in Matthew.
And God is still with us, He will never leave us nor forsake us. That’s the Good News that we are to spread to the world. That is the hope that we have as Christians. It is that hope that sustains us and gives us our joy. A joy that no one can take from us because “nothing can separate us from the love of God”. Nothing, absolutely nothing, no time, no where!!!! Rejoice, for a child is born!
