God dwells in the human being from the moment of creation, He dwells in the three divine persons: Father, Son and Holy Spirit, His presence in the human being has fruits; joy, prayer, knowledge of the vocation but above all and in a world so devalued, in their beliefs and in their feeling as children of God, this: man needs to find God in himself, to find the hope that perhaps he has lost because of the invasion of evil in his environment.The history of the Church shows great battles in the defense of the Faith, persecutions, children of God who fight not to silence their vocation, their essence and the meaning of their life; their Faith! In Mexico at the end of the 20's and beginning of the 30's; as a result of the persecution called the Cristero War, friends of Christ arose, who were taken to the honor of the altars, 25 Mexican saints, who gave their lives so that today, we can praise God in songs, joy and love. In this article we will discuss the testimony of these men who exalted their own vocations, men of the 20th century canonized on May 25, 2000 for their sanctity.
