"That you may prove what is that good and acceptable and perfect will of God." (Rom. 12:2) "Therefore do not be unwise, but understand what the will of the Lord is." (Eph. 5:17) "For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart." (Heb. 4:12)

Sometimes, the air in a room may look fresh and clean. However, when the bright sunlight penetrates the room, dust and other impurities can be clearly seen. In a similar way, when we study God's word, we begin to see impurities. With God's help, and the power of His word, we can clean up those impurities and be more like our Creator.
