I’ve witnessed those who have allot of zeal in attempting to serve the Lord, yet people who attack others in their faith (aside from addressing sin) is unmerited and abusive, often from a deep seated and self righteous pride, which is obviously not detected from those who practice such pettiness…
Romans 2: 1-4 speaks of how the Lord views such people.
1 Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things.
2 But we are sure that the judgment of God is according to truth against them which commit such things.
3 And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God?
4 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
