Normally when we judge someone, we measure ourselves against them. If someone murders, for example, we deem ourselves worthy to judge them because we've never murdered. In this way we "compare ourselves one with another" which is not wise because we conclude we are better than the murderer - their moral superior.
Jesus judges not by outward appearance or even actions - he looks upon hearts and judges accordingly. He said if we hate our brother we're a murderer, if we lust we've committed adultery. If we judge by surmising we are better than someone else we are unwise - we can only judge righteous judgment by fully submitting ourselves to the only righteous judge - Jesus. Then, it is he alone who is morally superior and not we ourselves.
"For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise." Brethren - do not compare yourselves with one another and especially do not compare yourself with your pastor or any other leadership in your life. Don't give in to the Babylonian religion where your entire self-worth is dependent upon what your pastor thinks of you. You minister at your pastor's pleasure, as he sees fit - he judges what you can and can't do within the confines of the church where he has total authority.
In Babylon, men exalt themselves over one another - they exalt and bow down to flesh - they create a system of relating void of godly love - refusing to serve, rather choosing to be served. They convince you that works of service unto them are what God will use to build godly character in you, and He may yet do this but it is not his ideal. God's ideal is that they model servant hood by serving you, not requiring you to serve them. In Babylon, everyone is over or under someone - they claim this is of God, but it is of the god of this world, not our God, who consistently modeled servant hood for us, though He was above all.....
