"We do not shuffle into this grace; we are introduced and presented, standing erect on our feet. "Ah but", you say, "I have been a vile sinner. I have been a terrible sinner - how can I possibly go into the Presence of God with boldness?". My reply to that is that if you do not go in with boldness, then you do not enter by faith. Realize that you go in Christ's hands, that His righteousness is upon you and that He leads you in".
Dr Martyn Lloyd-Jones - "Romans: Assurance (Romans 5)" - Banner of Truth Trust, Edinburgh (1971) - (p41).
