truth about the knowledge

English Notes: 

Goblet: 3:211 And to enable you to distinguish the pretenders (hypocrites) from the upstanding ones, fight with the words of truth against them and put them to the proof and test so that you understand how to recognise their attitude (mentality) because they only speak with their mouth, but not with truth about the knowledge, so they are going astray in their speaking.
