Don't Lift Yourself Up. Lift Up Others.
Christians have earned the stereotype (unfortunately) of being judgmental and haughty. However, our faith is based in the understanding that we are all 'perfectly imperfect'. We all stand in need of God's grace. Our job is to not to judge each other. Instead we are to be encouragers of each other. Be a friend. There is no competition in God's eyes. We all have room to grow.
Romans 12:3 "Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the faith God has distributed to each of you."
