Pg. 795 to 796 Satan is useful in vigilance and fight

Jesus says:

Well, My love does, with regard to Satan, what My hand is doing now. It destroys the cobweb. Look now the spider runs away and hides. It is afraid of what is stronger. Satan also is afraid of what is stronger. And what is stronger is Love.

Would it not be better to destroy the spider? asks Peter
It would be better. But the spider is doing its duty. It is true that it kills the poor little butterflies, which are so beautiful, but it exterminates a large number of filthy flies, which carry diseases and infection from sick to healthy people, from corpses to living persons. says Jesus.

Simon says: But in our case what does the spider do?

Jesus says: What does it do Simon? It does what your good will does. It destroys tepidity, apathy, vain conceit. It compels you to be vigilant. What makes you worthy of prize? Struggle and victory. Can you win if you do not fight? The presence of Satan compels continuous vigilance. Love, then, Who loves you, makes his presence not necessarily harmful. If you keep close to Love, Satan will tempt but he will be rendered unable to cause real damage.

Simon says: Always?

Jesus says: Always. In great and little things. For instance, a little thing: he in vain advises you to take care of your health. A treacherous piece of advice to try to take you away from Me. But Love holds you tightly, Simon, and your pains become of no importance even in your eyes.
