After their prayer had ended, the Savior gave the Nephites important counsel to keep a prayer continually in their hearts. Elder Russell M. Nelson of the Quorum of the Twelve Apostles similarly declared:
“Prophets have long told us to pray humbly and frequently. …
“Prayers can be offered even in silence. One can think a prayer, especially when words would interfere” (in Conference Report, Apr. 2003, 5; or Ensign, May 2003, 7).
President Boyd K. Packer, President of the Quorum of the Twelve Apostles, taught:
“Learn to pray. Pray often. Pray in your mind, in your heart. Pray on your knees. …
“Prayer is your personal key to heaven. The lock is on your side of the veil [see Revelation 3:20]” (in Conference Report, Oct. 1994, 76–77; or Ensign, Nov. 1994, 59).
