The more desperate your case, the more serious you will be. She can help you instantly with little things, in a sweet and gentle voice with an answer to your questions. Or, if you have a more serious concern, take the time to compose a novena of prayers in her honor. A novena is a way of praying of the same prayers for 9 consecutive days. You should compose a private prayer format of your own.
Personal prayers are very powerful.
Repeat your prayers every day for 9 consecutive days. She will help you immediately. Sister Josefa can help in every area of life.
