Like Abraham, you must never look at yourself again, and at all that is so true of you. You are justified in spite of all that; it is what God has done in Christ. Look to that, rest on that, be confident in that. Hold up your head with boldness; yea, I say it with reverence, go even into the presence of God with ‘holy boldness’ and in ‘the full assurance of faith’; not boldness in yourself, but in your Mediator, in your great High Priest, in the One whom God raised from the dead in order to let you know that your sins were dealt with at the Cross once and for ever, and that He looks upon you as His dear child.
-Martyn Lloyd-Jones, Romans, p. 250
