The steady endurance held onto within is what preserves a person through the season of testing that comes over the whole lower nature. The hour of temptation is the interval when the trial rises against everything that lives in the outward, earthly condition, the pull of the flesh and the world testing what a person is made of. Those who dwell upon the earth are the faculties still bound to the material and sensory life, and they are the ones put to the proof. The awareness that has kept the inner word of patient waiting is carried through that hour intact, held above the trial rather than swept into it. In plain terms, the part of a person that has practiced quiet steadiness is the part that survives when the testing comes.
Hour of temptation: the interval of trial that rises against the lower nature, the season when the flesh and the world put a person to the proof.
Earth: the outward, material and sensory condition of a person, the ground where the faculties still bound to the body dwell and are tested.
