I believe that we need to judge ourselves at the beginning to realize that we are sinful and in need in Jesus for salvation. After that, however, who are we to say we have done enough? Is that not promoting self-righteousness?
Don't get me wrong, I strongly believe that we are called to do good works, but those good works spring out of the source of love that God has given us to share with others. They are not meant to be a measuring device with which we judge or promote ourselves.
"Why do you judge your brother or sister? Or why do you treat them with contempt? For we will all stand before God's judgement seat."-Romans 14:10
