When one believes that they have the sole truth or path to the truth or believe that they ALONE are in "the light", that arrogance is the furthest thing from humility.
Everytime a JW mentions how they are in the truth and how they pity those who aren't, they are arrogant and have put themselves in the place of Jesus as Judge.
Everytime a JW says how they yearn for the end of "the system of things" so they can be in Paradise, they spew arrogance that is an afront to God and Jesus who are the SOLE deciders of WHO will be where and when.
Everytime a JW profess that the end of times is near, their arrogance is a slap in the face of Jesus who said "Neither I, nor the Angels, but only The Father knows".
