The enemy dialect
Other cultures also have their own dialects which express concepts that seem meaningful to them. The enemy's dialect repays study, because it can tell us much about how the enemy's mind perceives and frames the world.
Here is a good example of what I mean. Read it thoughtfully and you'll see how the terminology and expressions frame ordinary events and people in terms of an entirely alien world-view, concepts meaningless outside that context. "The world", for example, means something very different here than what it means in everyday English. "Sin", of course, doesn't mean the same thing as "crime" or "action that harms someone else" or any other concept relevant to the real world -- it means transgression of the arbitrary taboo system of a particular religion, and the word is meaningless outside the context of a subculture which takes such a taboo system as absolute.
Read the piece and you'll see plenty of other examples. This is a mentality as alien as that of any primitive tribe, yet it is widespread in our own country, even occupying a powerful position in one of our two political parties.
And it's a mentality that feels driven to dominate, and ultimately replace, any world-view different from itself. That's the meaning of "the Great Commission", another key term in this dialect. Everyone must be "drawn to Jesus", every brain must be occupied and reconfigured to think like these people do -- including yours. The only question is how.
