"If you invoke the Blessed Virgin when you are tempted, she will come at once to your help, and Satan will leave you." St John Vianny

It is good to remember one of the reasons Jesus from the cross entrusted us to Mary.  He knew that though he broke the bondage Satan had over us, the Evil one will still come after us. Mary is the Immaculate Conception, who crushed the head of Satan. Thus, the Tempter is afraid of her. Invoking her in times of temptation is like raising a protective wall between us and the the father of lies. Mary, help of Christians be our protector against the the Evil One.
