But He answered, “It is written: Man must not live on bread alone but on every word that comes from the mouth of God.”
The Bible is very special because without it no Christian can grow into a mature man of God, have the armor of God on and be strong enough to defeat the devil. We eat food because our bodies need the nourishment that food provides well, in the same way the word of God gives nourishment to our spirit and strengthens our faith in Christ so that we might live a life that pleases Him and have the strength to fight against the demonic deception. The word of God acts like a filter that the more you read the Bible the better your filter gets. The filter works like this: imagine someone comes to your door and want’s to share with you their “holy book” (The Book of Mormon, The Watchtower Magazine, The Qur’an) or even if they bring a Bible. How do you know that what they are saying is false doctrine or if from the Bible, interpreted correctly? If you know the Scriptures very well than anything that contradicts the Scripture you will pick up on it, having no affect on you whatsoever. Like a filter that doesn’t let anything through that would harm your body so in the same way your spiritual filter will keep false doctrine from taking root in your heart.
