We cannot attain to the understanding of Scripture either by study or by the intellect. Your first duty is to begin by prayer. Entreat the Lord to grant you, of His great mercy, the true understanding of His Word. There is no other interpreter of the Word of God than the Author of this Word, as He Himself has said, "They shall be all taught of God" (John 6:45). Hope for nothing from your own labors, from your own understanding: trust solely in God, and in the influence of His Spirit. Believe this on the word of a man who has experience.
Martin LutherThe spiritual rest, which God particularly intends in this Commandment, is this: that we not only cease from our labor and trade, but much more, that we let God alone work in us and that we do nothing of our own with all our powers.
Martin LutherThis life therefore is not righteousness, but growth in righteousness, not health, but healing, not being but becoming, not rest but exercise. We are not yet what we shall be, but we are growing toward it, the process is not yet finished, but it is going on, this is not the end, but it is the road. All does not yet gleam in glory, but all is being purified.
Martin Luther
