Your first task is to be dissatisfied with yourself, fight sin, and transform yourself into something better. Your second task is to put up with the trials and temptations of this world that will be brought on by the change in your life and to persevere to the very end in the midst of these things.
Let necessity, and not your will, slay the enemy who fights against you.
Now, justification in this life is given to us according to these three things: first by the laver of regeneration by which all sins are forgiven; then, by a struggle with the faults from whose guilt we have been absolved; the third, when our prayer is heard, in which we say: 'Forgive us our debts,' because however bravely we fight against our faults, we are men; but the grace of God so aids as we fight in this corruptible body that there is reason for His hearing us as we ask forgiveness.
