Elder Neil L. Anderson said, "Brothers and sisters, we each have moments of spiritual power, moments of inspiration and revelation. We must sink them deep into the chambers of our souls. As we do, we prepare our spiritual home storage for moments of personal difficulty. Jesus said, “Settle this in your hearts, that ye will do the things which I shall teach, and command you.” (see footnote Luke 14:27b) (You Know Enough by Elder Neil L. Andersen)
In those times of "spiritual power, moments of inspiration and revelation" our testimony of the Gospel of Jesus Christ increases. We come to know of the reality of a Living God who hears and answers and prayers. We come to know that Jesus Christ indeed lives and will come to the earth again. We come to know that the prophets speak with God and know God's will for us.
I can't see how we have those moments if we are not studying and pondering the scriptures and the teachings of the living prophets. Each of us must make the time to quietly and reverently sit and read and study and ponder ... so that we can "settle these things in our hearts"
In these perilious times, the saving forces will be the testimony of individual members and the Priesthood.
Are we shoring up our testimonies?
