A new heart

I just read Ezekiel 36 this morning for my devotions.  I was reminded how clear this passage is in support of God's sovereign initiative in salvation.  He acts, we respond, and it is all for the sake of His holy name.  He gathers His own.  He cleanses us.  He gives us a new heart and a new spirit.  And then, we will remember our evil ways and loathe ourselves for our iniquities.  It looks to me that regeneration comes before repentance.
