The Saints of the Most High have a constant prayer in their hearts, a perpetual yearning for the things of God. It is not that they are expected to be uttering prayers beneath their breath every minute of the day, for such could rapidly turn to a meaningless and empty ritual. Rather, in addition to regular prayers in our minds, we are asked to think wholesome thoughts and ponder on worthwhile matters.
“Whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things” (Philippians 4:8). The Lord has thus commanded us to “let the solemnities of eternity rest upon your minds” (D&C 43:34). Compare Alma 37:36-37; Proverbs 3:5-6.
