With each ordinance is a covenant—a promise. A covenant made with God is not restrictive, but protective. Such a concept is not new. For example, if our water supply is not clean, we filter the water to screen out harmful ingredients. Divine covenants help us to filter out of our minds impurities that could harm us. When we choose to deny ourselves of all ungodliness,36 we lose nothing of value and gain the glory of eternal life. Covenants do not hold us down; they elevate us beyond the limits of our own power and perspective. – Russell M. Nelson, “Personal Preparation for Temple Blessings,” Ensign (CR) May 2001
