I had an aunt who owned a pet ocelot.  One night, a man with a gun tried to rob her.  That ocelot loved my aunt beyond anything in the world.  The ocelot bit off the robber's forearm.  God is that kind of protector for us.  We do not have to earn that protection with good works.  Our faith is enough to ensure that God will always be with us.  We look at a couple of the letters of Paul to see just what God's grace - that unearned grace, given through faith alone - can do to transform us.
