let us realise that we must not come before God to plead our case, for we are all obliged to be condemned without his conducting a long trial against us, and all the more must our sins be compounded, since we think we have many defences and excuses to offer. So, there is no other remedy except acknowledging we are all indebted to him and asking for his pardon and mercy. This is how we must come to God: we must not claim to be righteous or be able to satisfy him; we must acknowledge the sins we have committed and ask him to receive us out of his pure kindness and mercy, and we must not open our mouths to plead our case, for that debate is not ours. That office is in the hands of our Lord Jesus Christ. As for us, let us keep our mouths shut and allow Jesus Christ to be our advocate and intercede for us so that our sins may be buried in this way and we may be absolved instead of condemned. That is the first thing we have to remember. And that is how we will be forever delivered by our Judge, as Paul says: ‘Who will lay anything to the charge of God’s children, since he justifies them?’ (Rom. 8: 33) Who will bring a suit against them, since Jesus Christ has taken their case in hand and wants to plead it? That, I say, is our only refuge, and without it we are lost and have no need to think about approaching God, for we will be struck down by his wrath, as we deserve.
