Why are people always so judgemental?

Sometimes the worst critics have low self-esteem, and push someone else lower to make themselves feel higher. How you perceive your own self is what's important for you. If you are a Christian, you have become a Child of God, and He loves you dearly. You know God has not completely perfected you yet, but He will in due time. Criticism and judgment are painful to endure, but you know you are blessed.
