At all times, God sends his servants to Earth. The time and place in which the saints lived and shone with their virtues is never accidental. Each saint, depending on his deeds, is given his own grace. Therefore, they resort to them in different needs and under different circumstances. Our book contains biographies of only some saints. This, of course, is only a small part of the overall feat that the faithful followers of God have accomplished throughout the existence of mankind. We hope that our works will benefit readers and help them get acquainted with the miraculous world of spiritual existence.
