Most Christians forget what Paul said, "But if we judged ourselves, we would not come under judgment" (1 Corinthians 11:31). We escape the critical judgment of God by exercising our own critical self-judgment.
A.W. Tozer said it beautifully with this quote.
The only proper attitude for the learner is one of humble self-distrust. "I am ignorant," he says, "and am willing to be taught. I am wrong and am willing to be corrected." In this childlike spirit, the mind is made capable of improvement.The writer of Hebrews wrote in Hebrews 4:12
For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.
When you judge others, you define yourself. Unknown
