Meditatio

"You must always have God's Word in your heart, upon your lips, and in your ears.  But where the heart is idle and the Word does not sound, the devil breaks in and has done the damage before we are aware [Matthew 13:24-30] .  On the other hand, the word is so effective that whenever it is seriously contemplated, heard, and used, it is bound never to be without fruit [Isaiah 55:11; Mark 4:20].  It always awakens new understanding, pleasure, and devoutness and produces a pure heart and pure thoughts [Philippians 4:8].  For these words are not lazy or dead, but are creative, living words [Hebrews 4:12]."

(LC 1:100-101)
