God cares for his sons. He cared for his son, the nation of Israel -- though they were rebellious. He cared for his Son, Jesus -- though Herod raged against him. He even cares for his newly adopted sons -- though we do not deserve it. God cared for us by sending his Son to deliver us from the corruption of sin and transform us into sons just like Jesus. That work of Christ gives us peace that only sons can have.
Christ Came into the World to Save the Worst Sinners too
The light of the world brings sight to the blind and judgment to the blinded. Faith means seeing Jesus as Savior: like the bronze serpent, we look on him and live. We were born in the blindness of sin, and without the light of Christ we could not find a way to safety. Christ comes to shine his light into our darkened eyes that we might see him and live. Yet for those who refuse to see their Savior in Christ, the blindness of unbelief remains. He Gives gracious sight to the blind who trust in him; he gives blinding judgment on those who reject him; finally, he displays the work of God in the lives of those who now walk in the light of Christ.
