The heart is deceitful above all things, and desperately sick; who can understand it?  (Jeremiah 17:9 ESV)

This passage tells us many things but one thing it tells us is that we never get to the bottom of our sinfulness!  It is deeper than we can fathom.  If you think you have seen the depth of your own sinfulness, there is more, much more.  But God does not leave us here.  He provides the remedy to our deep and desperate sinfulness.  It is found in 1 Peter 1:3:

Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead. (1 Peter 1:3 ESV)

The depth of sour sinfulness leaves us helpless and hopeless to save ourselves.  Salvation is not a self help program.  It is not a work of man but a work of God.  According to his great mercy, he caused us to be born again.  Who is he?  It is God the Father.  That is the reason Peter explodes with worship and exaltation . . . Blessed be the God and Father of our Lord Jesus Christ!  We do not, we cannot save ourselves!  Salvation is the great work of mercy toward pitiful creatures who are bound up in their sin, unable to free themselves.  We are so bound up in our sin we do not realize it is bondage but as our freedom to be ourselves, to do what we want!  Peter says God the Father caused us to be born again.  He caused it, he initiated it just as a human father and human mother initiate and creates life. 
This week, celebrate the wonderful truth that God is your Father because he cause us to be born again, he created new life in us so that we respond in faith.  Faith is the fruit of being born again, regenerated, by God.  That is the reason he is your Father!
