They think we can "weed out" the parts that don't fit with our modern lives and contemporary thought. But that has been the devil's deception for over 6,000 years, since he first spoke his lies to Adam and Eve in the Garden of Eden.
The Word of God ... The Bible ... is synonymous with Jesus Christ. It is the written, spoken, living and unfailing Truth that leads to our salvation.
It is more than our "guide through life" ... it is our "path to everlasting life" and must be our one standard to follow.
"Sanctify them through thy truth: thy word is truth."
"In the beginning was the Word, and the Word was with God, and the Word was God."
For the word of God is quick, and powerful, and sharper than any two edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
