Isaiah 45 - 48

God sends a prediction of a coming leader named Cyrus.  This one would accomplish God's plans perfectly.  Yet, God would prove that only He could provide safety and salvation.  God stresses over and over that only He can provide salvation because only He is God.  Babylon is slated to feel the wrath of God's punishment because of her refusal to listen to the voice of God.  Even through this, Israel would demonstrate that God can provide and redeem her for His good pleasure.
