Intellectual power, physical stamina, and the length of life depend upon immutable laws. Through obedience to these laws, man may stand conqueror of himself, conqueror of his own inclinations, conqueror of principalities and powers, of “the rulers of the darkness of this world,” and of “spiritual wickedness in high places” (Ephesians 6:12).—Prophets and Kings, 488, 489 (1917). {2MCP 406.5}

Både åndsevnerne og den fysiske styrke kontrolleres (407) af uforanderlige love. Ved at styrke vore evner kan mennesket vinde sejr over sig selv, sine egne tilbøjeligheder, magter, "verdensherskerne i dette mørke" og "ondskabens ånde-magter i himmelrummet". Ef. 6,12. — Profeter og konger, 238 (1917).
