Judging helps to sanctify the individual believer, prepares us to do the work of God, protects us from heretical doctrine that jeopardizes our faith, makes us an effective witness for Christ, and is a demonstration of God's grace to others.
Judge Yourself
"Sanctify them through thy truth: thy word is truth." John 17:17
Judging ones' self with the Word of God is a key part of the process of sanctification through which every believer proceeds. This is why we are told to examine ourselves to see if we be in faith. (II Corinthians 13:5)
