Ephesians 3:19

And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.  

Jesus loved us so much that He took all our sins and failings on the cross.  That loved nailed to a tree lets us be able to get closer to God and know His ways.  Without that love, we would never be able to be overcomers on this earth.  God can reach down and work on our behalf.  Love sets us free.
