Recommended Book: First Epistle of Clement to the Corinthians - Kindle Edition (get Kindle app for phone) (paid link)
The mere name of Jesus is sufficient to vanquish all the powers of hell. St. Paul says that God has given to Jesus Christ a name which is above every name, since it is at that name that everything is made to humble itself: He hath given Him a name which is above all names; that in the name of Jesus every knee should bow, of those that are in heaven, on earth, and under the earth. In contending with the enemies of our salvation, it often avails more to victory to call to our aid the name of Jesus than to say many long prayers.
