Faith, constant meditation on the Scriptures, obedience, humility, . . . 3. "Faith cometh by hearing, and hearing by the word of God" (Romans 10:17). The Scriptures purify, instruct, strengthen, enlighten and inform. The blessed man will meditate in them day and night. 4. To be entirely safe from the devil's snares the man of God must be completely obedient to the Word of the Lord. The driver on the highway is safe, not when he reads the signs but when he obeys them. So it is with the Scriptures. To be effective they must be obeyed. 5. Again, there is a close relation between humility and the perception of truth. "The meek will he guide in judgment: and the meek will he teach his way" (Psa. 25:9). In the Scriptures I find no shred of encouragement for the proud. Only the tame sheep can be led; only the humble child need expect the guidance of the Father's hand. When all the evidence is in it may well be found that none but the proud ever strayed from the truth and that self-trust was behind every heresy that ever afflicted the church.
