Our Lady of the Sierras

(Pat) “Prayer began with opening song “Immaculate Mary”, opening prayer, and scripture reading (1 Peter 4:7-11). After scripture reading, a reflection was presented referencing the previous Friday night’s scripture relating of Psalm 46 versus 11 …. “Be still and know that I am God!” In recollection, it was relayed that one of the first verbal messages given by Our Lady simply said, “Be calm, be silent and love much”. It was suggested that the “be calm” meant “be still”….and “know”…. a silence of the heart, mind, body and soul whereby we can hear the word of God. In the processes of calmness, and silence we experience the presence of God through “loving much” with the grace of the love of God.

First Vision of August 29, 2014

(Pat) El rosario comenzó con la canción "María Inmaculada", la oración de apertura y lectura de la Sagrada Escritura (1 Pedro 4:7-11). Después de la lectura bíblica, se dio una reflexión con referencia a la lectura del Salmo 46 verso 11 del viernes anterior…. “¡Paren y reconozcan que soy Dios!” Haciendo una reflexión, Pat mencionó que Nuestra Señora dijo en uno de sus primeros mensajes: “Tengan calma, guarden silencio y tengan mucho amor”. Sugirió que “Tengan calma” significa “paren”… y “reconozcan”…. un silencio de corazón, mente, cuerpo y alma donde podamos escuchar la palabra de Dios. Durante este proceso de tranquilidad y silencio, experimentamos la presencia de Dios “amando profundamente” con la gracia del amor de Dios.
