"and he will delight in the fear of the Lord. He will not judge by what he sees with his eyes, or decide by what he hears with his ears;" NIV translation
The "fear of the Lord" that it speaks of here is awe and it is an appreciation for the nature of God and His work. We see, here, that Jesus will not judge our salvation based on works or words that we say. Our salvation is based on the grace of God alone. Most people, (even Christians & pastors too), try to add some amount of work to the concept of grace but, once you add any work to grace, you no longer have true grace. This adding a little law to grace is why there are so many denominations and independent groups instead of a united body of Christ as God desires.
