Several years ago, Time Magazine published a segment titled The 25 Best Inventions of 2015, in which they listed a bevy of innovative inventions and cutting-edge gadgets that make the world a better place. Each gizmo and doodad enhances the quality of everyday life, but one invention stands above the rest: the Drinkable Book. Created by Theresa Dankovich, a researcher at Carnegie Mellon University, the Drinkable Book contains silver-infused pages that can be used to filter contaminated water. Just one page filters up to 100 liters of water, providing a cost-effective solution for impoverished communities who do not have access to clean drinking water. The book’s purifying pages ensure survival for people who would otherwise perish from bacterial infections and other deadly waterborne diseases—the book is literally life-saving.

There is another kind of Book that cleanses—one that may be found on the nightstand, the pulpit, or the pew: the word of the living God, the Bible. Inspired by the Holy Spirit, the Scripture contains sanitizing pages that filter the bacteria of evil from our lives. Each passage in God’s word is infused with sin-killing, iniquity-cleansing, wickedness-purifying truth that sanctifies us from sin unto God. That is why Jesus prayed, “Sanctify them in the truth; your word is truth” (John 17:17). Without its disinfecting truth, we will suffer from sin-infections contracted from worldly corruption, heart-borne evils, and false teaching.

The human heart flows with the “springs of life” as Solomon wrote, but because the heart is also “desperately wicked,” it spews tainted water that toxically contaminates all of existence (Proverbs 4:23; Jeremiah 17:9). Therefore, we need the truth of Scripture to pierce our innermost being and expunge us of evil (Hebrews 4:12). It is only by His “precious and very great promises” that we are cleansed of defilement (2 Peter 1:4). Nothing but the “whole counsel of God” can flush the mind of the muck of error (Acts 20:27; cf. 2 Timothy 3:16). As the psalmist aptly confessed, “How can a young man keep his way pure? By guarding it according to your word” (Psalm 119:9).

Filter your heart’s fountain with God’s word. Sift all ideas and teachings through the pages of Scripture before you drink them in. Clean off the dust from your Bible so God may use it to clean you. “Now ye are clean through the word which I have spoken unto you” (John 15:3, KJV).
