In his illustration at Mathew 13: 24-30, Jesus made it clear that the wheat and weeds were to grow together until the harvest. This parable runs contrary to the concept put forward by the WT about getting out of the world and running to their organization for salvation.
First of all, the parable says that the weeds will be gathered, bundled and burned first – THEN the wheat will be gathered into the storehouse.
WT teaches that we need to gather up the wheat FIRST. Not only are they doing it backward, they are teaching that true Christians must isolate themselves inside a special ‘wheat’ organization, separate from the weeds. That completely defeats the point of the parable.
A poster on Y!A made this comment:
You would also notice in that illustration that Jesus clearly identified the field as being the world of mankind here on earth. Therefore removing the wheat from the field to the storehouse must symbolize removing Christians from the world of mankind - gathering them to heaven - the kingdom in which they will "shine as brightly as the sun". The storehouse cannot represent a restored true congregation *on earth* because being on earth is denoted by being in the field (Matthew 13:38,43)
Also, you would notice that at the harvest time it is the weeds that are removed from the wheat and bundled. But JWs say the converse - that the wheat are removed from the weeds and put in a restored congregation of their own. If that were so Jesus' illustration would instead speak about the reapers collecting the wheat out from the weeds and transplanting them to a specially cleared corner of the field that free of weeds, to grow for a while before finally gathering them into the storehouse. That is how the JW interpretation would have to be pictured by the illustration, based on Jesus' own clarification of the symbols.
