In his book Precious Remedies Against Satan's Devices, Thomas Brooks counsels the believer to consider whether or not he seriously meditates on the Word of God:
"It is not he who reads most--but he who meditates most, who will prove the choicest, sweetest, wisest, and strongest Christian...Know that it is not the knowing, or the talking, nor the reading man--but the doing man, that at last will be found the happiest man...Reader, If [sic] it is not strong upon your heart to practice what your read, to what end to you read? To increase your own condemnation? If your light and knowledge be not turned into practice, the more knowing a man you are, the more miserable a man you will be in the day of recompense; your light and knowledge will more torment you than all the devils in hell. Your knowledge will be that rod that will eternally lash you, and that scorpion that will forever bite you, and that worm that will everlastingly gnaw you; therefore read, and labor to know, that you may do--or else you are undone forever." (Kindle location 238-248).
"But be ye doers of the word, and not hearers only, deceiving your own selves. For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: For he beholdeth himself, and goeth his way, and straightway forgetteth what manner of man he was," (James 1:22-24).
