When Christ's Visible Presence was Withdrawn, the word of God was to be our Source of Power

The life of Christ that gives life to the world is in His word. It was by His word that Jesus healed disease and cast out demons; by His word He stilled the sea, and raised the dead; and the people bore witness that His word was with power. He spoke the word of God, as He had spoken through all the prophets and teachers of the Old Testament. The whole Bible is a manifestation of Christ, and the Saviour desired to fix the faith of His followers on the word. When His visible presence should be withdrawn, the word must be their source of power. Like their Master, they were to live "by every word that proceedeth out of the mouth of God." Matt. 4:4. - The Desire of Ages, page 390.
