In our lives the oil of preparedness is accumulated drop by drop in righteous living. Attendance at sacrament meetings adds oil to our lamps, drop by drop over the years. Fasting, family prayer, home teaching, control of bodily appetites, preaching the gospel, studying the scriptures - each act of dedication and obedience is a drop added to the store. Deeds of kindness, payment of offerings and tithes, chaste thoughts and actions, marriage in the covenant for eternity - these, too, contribute importantly to the oil with which we can, at midnight, refuel our exhausted lamps"
(Spencer W. Kimball, Faith Precedes the Miracle, , 256).
