Knowledge without faith and understanding is quite likely to result in a lifestyle of value judging. We are value judging when we feel that others are not measuring up to what we perceive as right and wrong standards. In this situation, our values are founded on opinions we formed as a result of life experiences. We add God to our views to form a warped sense of justice and believe that this gives some sort of righteous approval for our judgmental and legalistic world view. All standards of conduct based on the opinions of hurting people are biased.
People operating from their own hurts are judgmental.
There is an inability to love others due to an inability to love self. Adding what we think is what God says only makes the problem worse. God doesn't need our opinions. Real self-esteem principles are not separate from Godly principles. In truth, Jesus is the perfect example of a person with healthy self-esteem.
