Jesus revealed that we pray to a wise Father who knows what things we have need of, before we ask Him.11
Mormon taught his son, Moroni, that we should pray “with all the energy of heart.”12 Nephi exclaimed, “I pray continually for [my people] by day, and mine eyes water my pillow by night, … and I cry unto my God in faith, and I know that he will hear my cry.”13
The sweet power of prayer can be intensified by fasting, on occasion, when appropriate to a particular need.14 – Russell M. Nelson, “Sweet Hour of Prayer,” Ensign (CR) May 2003
