Father Jacques Philippe said this quote

When individuals are close to God, love and desire to serve the Lord, the usual strategy of the devil is to cause them to lose their peace of heart, whereas God, on the contrary, comes to their aid to give them peace. But this rule is reversed for those whose hearts are far from God, who live in indifference and evil. The devil seeks to tranquilize such individuals, to keep them in a false sense of quietude, whereas the Lord, Who desires their salvation and conversion, will trouble and disquiet their consciences in an effort to get them to repent.
