What is the standard we go by and will be judged by?
The standard to go by and the standard by which we will be judged is the Word of God, not the ideas of men or denominations. Human groups may be untrustworthy, but God's Word is the authority we must follow and the measure for future judgment. It is what we have to go by.
Les explains that denominations cannot always be trusted because they are still only men. But the message is not men's idea; it is the Word of God. That Word is what we have to go by, and it is what we will be judged by someday. The contrast is between fallible human authority and the divine standard that is what we go by and what we will be judged by someday.
