Hebrews 13:20, 21

Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, make you perfect in every good work to do his will, working in you that which is the well pleasing in his sight, through Jesus Christ; to whom be glory forever and ever. Amen.  

God made a covenant with us through the shed blood of Jesus.  This covenant allows God to be able to work in our lives so we can fulfill the plan He set down before we were born.  So, we can be perfect in every good work and be well pleasing in His sight.  The covenant brings God’s ability to help us overcome and work miracles in this life.
