“In order to endure the trial before them, they must understand the will of God as revealed in His word; they can honor Him only as they have a right conception of His character, government, and purposes, and act in accordance with them. None but those who have fortified the mind with the truths of the Bible will stand through the last great conflict. To every soul will come the searching test: Shall I obey God rather than men? The decisive hour is even now at hand. Are our feet planted on the rock of God’s immutable word? Are we prepared to stand firm in defense of the commandments of God and the faith of Jesus?”

Great Controversy p. 593
