The book of Hebrews tells the wonderful story of a great heart transplant. Our holy and righteous Father made obsolete the Old Covenant which cleansed the body but not the heart, and sent his Son to establish a new and better Covenant so that we, like Jesus, could be made holy and righteous and enjoy perfect fellowship with our Father by receiving a new and perfect heart. With this new heart we can enjoy God's rest, strengthening and presence and should put it into action!
