We often hear members of the Church say that their testimony of the gospel is their most prized possession. It is a sacred gift from God that comes to us by the power of the Holy Ghost. It is the calm, unwavering certainty we receive as we study, pray, and live the gospel. It is the feeling of the Holy Ghost bearing witness to our souls that what we are learning and doing is right. – Craig C. Christensen, “I Know These Things of Myself,” Ensign (CR) November 2014
