Everyone needs "priests" to give us authorized external confirmation that we are good enough, but all of our earthly priests will fail us, consigning us to a life of perpetual struggle. Jesus, however, is better than every priest who ever lived, even the mysterious priest-king Melchizedek, because his offering for us was final, and his prayers for us are perpetual. His once-for-all sacrifice on the cross, and his constant intercession for us at the Father's right hand, enable us to engage in the imperfect, two-steps-forward, one-step-back work of sanctification without fear.
