"This is the terrible fix we are in. If the universe is not governed by an absolute goodness, then all our efforts are in the long run hopeless. But if it is, then we are making ourselves enemies to that goodness every day, and are not in the least likely to do any better tomorrow, and so our case is hopeless again....God is the only comfort, He is also the supreme terror: the thing we most need and the thing we most want to hide from." - C.S. Lewis from Mere Christianity

Lewis had a way of taking a truth and really hammering it home.  Nothing we do brings us to righteousness.  It's futile.  We can be as good we humanly can be, but it won't save us.  Lewis said we're making ourselves enemies to that goodness.  Well, what does that mean?  It means that even though we are aware of God, aware of His righteousness, our sin nature puts us at odds with God.  So, not only can we not be good enough to save ourselves, the bad that is in us it making us enemies of God.  This is not good.  God's justice demands our lives as payment for our sin (Romans 6:23a), as a result we really want to hide from Him. 

But that's not the end... 

Thank God we don't have to save ourselves.  Praise God for the calling of the Holy Spirit to our souls out of the darkness and the salvation of our lives through the atoning work of Christ alone!  Glory to God that our regenerate minds desire to do God's Will and when we do stumble our sin is forgiven and we are credited Christ's righteousness in exchange for our apology!  That is a truth that should knock you off your feet.  That truth is GOD'S PERFECT GRACE...

...and its really good!
