“If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just, to forgive us our sins, and to cleanse us from all iniquity. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.” — 1 Jn. 1:8-10

St. Francis de Sales:

St. Francis de Sales’ Consoling Words on Forgiveness and Self-knowledge

“The persons for whom I write are those only who are determined not to commit any fault deliberately, but who may stumble through surprise, inadvertence, and weakness, notwithstanding their resolution.

It usually happens that such persons are astonished and troubled at their faults, conceive a false shame for them, and fall into vexation and discouragement. These are the effects of self-love, and are much more pernicious than the faults themselves. We are surprised at falling: an evident mark that we scarcely know ourselves. We ought, on the contrary, to be surprised at not falling more frequently, and into more grievous faults, and to return thanks to God for the dangers from which He preserves us. We are troubled every time that we are beguiled into some fault, lose interior peace, are agitated, and spend hours, even days, thinking of it.

We should never be troubled; but when we find ourselves on the ground, arise tranquilly, return to God with love, ask His forgiveness, and reflect no more on what has occurred, unless when it is necessary to accuse ourselves of it.

We have a false shame for our faults; we can hardly venture to discover them to our confessor. “What idea will he have of me after so many promises, so many assurances, I have given him?”

If you declare your faults simply and humbly, he will have more esteem for you. If you have a difficulty in telling them to him, his confidence in you will diminish on account of your want of sincerity.

But the worst of all is that we are vexed at being vexed, and impatient at being impatient. What a misery! Should we not see that this is pride, that we are humbled on finding ourselves less holy than we had imagined, that we aspire to be exempt from imperfections and faults only in order to applaud and congratulate ourselves on having spent one day or week without much matter of reproach?

In fine, we are discouraged… we abandon our exercises one by one; we give up prayer … What will this constraint, we say, this continual watching over oneself, this struggle after recollection and mortification, avail us, since we correct nothing, fall incessantly, and never become better?

There is not a craftier snare of the demon than this.

Would you wish to be protected from it? Never be discouraged, and no matter what fault you happen to commit, say:

Though I should fall twenty times, or a hundred times, a day, I will arise at every fall, and pursue my course. What does it amount to, after all, that you should have met with some accidents on the way, provided you safely reach the journey’s end? God will not reproach you after your recovery.”

7 “Judge not, that you be not judged. ² For with the judgment you pronounce you will be judged, and the measure you give will be the measure you get. ³ Why do you see the speck that is in your brother’s eye, but do not notice the log that is in your own eye? ⁴ Or how can you say to your brother, ‘Let me take the speck out of your eye,’ when there is the log in your own eye? ⁵ You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your brother’s eye.”
