Sweet Mother, can faith be increased by personal effort?

Faith is certainly a gift given to us by the Divine Grace. It is like a door suddenly opening upon an eternal truth, through which we can see it, almost touch it.
     As in everything else in the ascent of humanity, there is the necessity -especially at the beginning of personal effort. It is possible that in some exceptional circumstances, for reasons which completely elude our intelligence, faith may come almost accidentally, quite unexpectedly, almost without ever having been solicited, but most frequently it is an answer to a yearning, a need, an aspiration, something in the being that is seeking and longing, even though not in a very conscious and systematic way. But in any case, when faith has been granted, when one has had this sudden inner illumination, in order to preserve it constantly in the active consciousness individual effort is altogether indispensable. One must hold on to one's faith, will one's faith; one must seek it, cultivate it, protect it.
     In the human mind there is a morbid and deplorable habit of doubt, argument, scepticism. This is where human effort must be put in: the refusal to admit them, the refusal to listen to them and still more the refusal to follow them. No game is more dangerous than playing mentally with doubt and scepticism. They are not only enemies, they are terrible pitfalls, and once one falls into them, it becomes tremendously difficult to pull oneself out.
     Some people think it is a very great mental elegance to play with ideas, to discuss them, to contradict their faith; they think that this gives them a very superior attitude, that in this way they are above "superstitions" and "ignorance"; but if you listen to suggestions of doubt and scepticism, then you fall into the grossest ignorance and stray away from the right path. You enter into confusion, error, a maze of contradictions. ...You are not always sure you will be able to get out of it. You go so far away from the inner truth that you lose sight of it and sometimes lose too all possible contact with your soul.
     Certainly a personal effort is needed to preserve one's faith, to let it grow within. Later-much later-one day, looking back, we may see that everything that happened, even what seemed to us the worst, was a Divine Grace to make us advance on the way; and then we become aware that the personal effort too was a grace. But before reaching that point, one has to advance much, to struggle much, sometimes even to suffer a great deal.
      To sit down in inert passivity and say, "If I am to have faith I shall have it, the Divine will give it to me", is an attitude of laziness, of unconsciousness and almost of bad-will.
      For the inner flame to burn, one must feed it; one must watch over the fire, throw into it the fuel of all the errors one wants to get rid of, all that delays the progress, all that darkens the path. If one doesn't feed the fire, it smoulders under the ashes of one's unconsciousness and inertia, and then, not years but lives, centuries will pass before one reaches the goal.
      One must watch over one's faith as one watches over the birth of something infinitely precious, and protect it very carefully from everything that can impair it.
      In the ignorance and darkness of the beginning, faith is the most direct expression of the Divine Power which comes to fight and conquer.
