Children of Peace or Problems: Shear-Jashub (Isaiah 7:1-9)

The people of Judah are facing a foreign and domestic threat that could impact their future existence.  Ahaz their king is scared that his kingdom will not be able to withstand a lengthy battle.  The Lord sends Isaiah to deliver a prophecy to Ahaz and he is to bring his son.  What is the significance of Isaiah’s child?  What is the hope that a remnant shall return?
