July 22, 1904 – Only stability is what reveals the progress of Divine Life within the soul.
Continuing in my usual state, blessed Jesus came for just a little and told me: “My daughter, when the soul proposes either not to sin or to do some good, and does not carry out the proposition she made, it is a sign that those things are not done with all of her will and that the divine light has had no contact with the soul. In fact, when her will is true and the divine light makes known to her the evil to be avoided or the good to be done, the soul hardly fails to execute what she has proposed.
On the other hand, when the divine light does not see stability in her will, it does not administer to her the necessary light in order to avoid something or to do something else; at the most, there might be moments of misfortune, abandonments by creatures or some other circumstance, such that it seems that the soul would want to undo herself for God, and change life; but as soon as the wind of the circumstances changes, immediately her human will changes.
So, instead of will and light, it can be said that there is a mixture of passions according to the changes in the winds. Stability alone is what reveals the progress of Divine Life within the soul, because, since God is immutable, one who possesses Him shares in His immutability in good.”
