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.
Christ is the Master; the Scriptures are only the servant. The true way to test all the Books is to see whether they work the will of Christ or not. No Book which does not preach Christ can be apostolic, though Peter or Paul were its author. And no Book which does preach Christ can fail to be apostolic, although Judas, Ananias, Pilate, or Herod were its author.
He who believes in God is not careful for the morrow, but labors joyfully and with a great heart. "For He giveth His beloved, as in sleep." They must work and watch, yet never be careful or anxious, but commit all to Him, and live in serene tranquility; with a quiet heart, as one who sleeps safely and quietly.
What is our death but a night's sleep? For as through sleep all weariness and faintness pass away and cease, and the powers of the spirit come back again, so that in the morning we arise fresh and strong and joyous; so at the Last Day we shall rise again as if we had only slept a night, and shall be fresh and strong.
