When the reproaches of your conscience, however well merited they may be, throw you into a state of trouble and depression; when they discourage and upset you, it is certain that they come from the devil who only fishes in troubled waters, says St. Francis of Sales.
The rebellion of the passions, and that excessive sensitiveness which causes one to be put out beyond measure on the slightest provocation ought not to disquiet, nor to discourage anyone suffering from them, nor to make him think that his desire of sanctification is not sincere. This mistake and the discouragement it occasions are more harmful than all the other temptations. To get rid of them, or to overcome them we must be well persuaded that these rebellions, and this extreme sensitiveness are sent to us by God to be the ground of our combats and victories; and that these little falls are permitted to help us to practise humility.
Looked upon in this light our falls will be incomparably more useful to us than victories spoilt by vain self-complacency. This is a very certain and a very encouraging truth. We must be convinced, thoroughly convinced that our miseries are the cause of all the weakness we experience, and that God, in His mercy, allows them for our good. Without them we should never be cured of a secret presumption and a proud confidence in ourselves. Never should we be able to rightly understand that all that is bad is ours, and that all that is good is from God alone. To acquire a habit of thinking thus it is necessary to pass through a great number of personal experiences, and there is a greater necessity for this the more deeply rooted these vices are, and the greater the hold they have on the soul.
You must never feel surprised at finding that a day of great recollection is followed by one full of dissipation; this is the usual condition in this present life. These changes are necessary, even in spiritual things, to keep us in humility, and a state of dependence on God. The saints themselves have passed through these alternations, and others still more troublesome. Only try not to give rise to them yourself; but should this, unfortunately, happen, then humble yourself peacefully and without vexation, which would be a worse evil than the original one; then endeavour to regain self-control, and to return to God; doing so quietly without over-eagerness, and by means of a total holy abandonment to God’s ways.
Oh! if only this interior abjection were accepted, loved and valued, no one would consent to be without it, because it brings the soul nearer to God. This great God has, in fact, declared that He draws near to those who humble themselves and who love to be humiliated. If it is good for us to be humbled in the sight of others it is no less useful to be annihilated in our own eyes, in our pride and self-love which are put an end to in this way. It is thus, in fact, that they are gradually extinguished in us, and for this purpose does God permit so many different subjects for interior humiliation. It only remains to know how to profit by them, by following the advice of St. Francis of Sales, and practising acts of true humility, gently and peacefully; and this will drive out false humility which is always in a state of vexation and spite.
Vexation and spite under humiliation are so many acts of pride, just as worry and irritation during suffering are so many acts of impatience. Let us not forget this, and let us take good care not to look upon the want of feeling we experience for the things of God as callousness; it is simply dryness, and a trial as inevitable and ordinary as distractions. If it is constant it is a still better sign, because it is in this way that God prepares the soul to proceed by pure faith, the most sure and meritorious way. - Jean Pierre de Caussade, Letter XVII
