For there is no one in the world so rooted in the devil that the good Spirit does not at times visit and move his heart. Likewise, there is no one so good that the devil does not try to touch him with temptation. 19 Many good and just people are tempted by the devil with God's permission. This is not because of wickedness on their part but for their greater glory.
20 The Son of God, one in divinity with the Father and the Holy Spirit, was tempted in the human nature he had taken. How much more are his elect put to the test for their greater reward! Again, many good people sometimes fall into sin, and their conscience is darkened through the devil's falsehood, but they get back up hardier and stand stronger than before through the power of the Holy Spirit. However, there is nobody who does not realize this in his conscience, whether the suggestion of the devil leads to the deformity of sin or to the good, if he would only think about and examine it carefully. And so, bride of my Lord, you do not have to be in doubt as to whether the spirit of your thoughts is good or bad. For your conscience tells you which things to ignore and which to choose. What should a person who is full of the devil do, since the good spirit cannot enter him inasmuch as he is full of evil? He should do three things. He should make a plain and complete confession of sins, which, even if he cannot be heartily sorry due to his hardened heart, still it benefits him inasmuch as, due to his confession, the devil gives him some respite and gets out of the good spirit's way. Second, let him be humble and resolve to atone for the sins he has committed and do what good he can, and then the devil will begin to leave. Third, in order to get the good spirit back again, he should beseech God in humble prayer and, with true love, be sorry for the sins he has committed , inasmuch as love for God kills the devil.
The devil is so envious and malicious that he would rather die a hundred times than see someone do God the least little good out of love."
