I'm with Mac, I believe what Paul is talking about here is that the works of the Holy Spirit are always directed towards the good of the elect. Paul makes it clear that we are incapable of knowing what is best for us, because we are incapable of knowing God's purpose and what he has predestined for us. It is clear from history, man does not know his own destiny or what he is capable of doing with God's help.
I am one of those that believe that God has complete sovereignty over all things. And that nothing happens without God knowing before hand and if it happens then he must've allowed to happen.
