What makes Good News good? Part three

Continuing thought on John Piper's sermon 'What makes the Good News good?'
God Alone gives light and takes blindness.
2 Cor 4:6

There's a link between this verse (2 Cor 4:6) and Genesis 1. Both times God gives light. In Genesis God speaks light into nothingness. God commands and nothingness obeys. There is hope here. At beggining of time God spoke into darkness and there was light...so why not into people's hearts? In fact, not just 'why not' but this is the only way that people will be saved. The only way. There was darkness in our hearts before we were saved, just as there was darkness in the world. 2 Corinthians 4:6 makes the link between the darkness in people's hearts and the darkness in the world. If you are a Christian you were saved. This was an event that happened, God shone His light into out hearts. Where there was dark: light, where there was blindness:
vision, where there was lostness: foundness (?!).
He shone His light into our hearts by His grace and mercy. No Christian thinks he saved himself. Blind people can not make themselves see, dead people can not become alive under their own steam. No. God is the only one who can shine light into our dark hearts, into anyone's dark hearts. He saved us, He shone His light when we were in total rebellion to Him and His ways. What an awesome, merciful, gracious God! Salvation comes when God speaks light into our hearts. Salvation comes when we see the light of the glory of God in the face of Jesus Christ. When we see that Jesus is God.
Thats why lostness is blindness to glory.
