The word stewardship calls to mind the Lord’s law of consecration (see, for example, D&C 42:32, 53), which has an economic role but, more than that, is an application of celestial law to life here and now (see D&C 105:5). To consecrate is to set apart or dedicate something as sacred, devoted to holy purposes. True success in this life comes in consecrating our lives—that is, our time and choices—to God’s purposes (see John 17:1, 4; D&C 19:19). In so doing, we permit Him to raise us to our highest destiny.
