Jesus Chooses the Twelve Apostles

In this passage Jesus gives authority to the 12 to cast out demons so far we have only met 5 of them so where he picked up the other 7 from I don't know. Interestingly he sends them out to preach - so the demon outcasting is just a side job. Is it just me or does it seem weird to you to mention those 2 functions in the same sentence? I mean we have pastors who go out and preach on a regular basis - but they don't do as much of the demon outcasting as this text might imply. What does that mean - there are less demons around today? (unlikely), or that we no longer have the authority to do it? (not true), I think most likely is that we just don't perceive them the same way that they were seen back then. We attribute their effects to other things, and try and solve things by ourselves. I'm not sure where I am headed with this train of thought - only that the same amount is out there, but we don't seem to be doing much about it (then again back then there were only 12 with authority, now there's a lot more so maybe we can handle it on a less regular basis per person).
