Psa 119:9-11 Wherewithal shall a young man cleanse his way? by taking heed thereto according to thy word. (10) With my whole heart have I sought thee: O let me not wander from thy commandments. (11) Thy word have I hid in mine heart, that I might not sin against thee.
Martin Luther spoke of this when he said, "I have before me God's Word which cannot fail, nor can the gates of hell prevail against it; thereby will I remain, though the whole world be against me. And withal, I have this comfort, that God says: I will give thee people and hearers that shall receive it; cast thy care upon me; I will defend thee, only remain thou stout and steadfast by my Word."
