Bufe talks about the mercy of God.  Most of us don't think too much about the mercy of God in the Old Testament.  We tend to think it is shown more in the New Testament but it is also in the Old Testament.  Bufe tells about Moses and the people in the wilderness.  We need to understand the justice of God to understand the mercy of God.  Bufe talks about 3 Hebrew words for mercy that God uses in Exodus 34.  God's love is constant and unconditional.  God displayed that love in the New Testament by sending His Son to die on the cross for our sins.  The dilemma to understanding Jesus' death on the cross is understanding that it is at the cross that justice and mercy meet.
