Yesterday at church we talked about following Christ and how this is actually very aggressive. Christians do not meekly cower (sp?) in a corner, trying to fend off the attacks of the devil. Belief and faith is offensive to Satan, and in some sense affects everywhere you go. There's no reason why not to take the power you get from worship with believers everywhere you go. These ideas correspond nicely to a few quotes I liked in the book I'm reading right now called
Organic Church. I will give you a couple of them:
Can the church stop its puny, hack dreams of trying to "make a difference in the world" and start dreaming God-sized dreams of making the world different?
If you wake up in the morning and don't run into the enemy head on, then maybe you're going in the wrong direction.
Jesus, about his Church: "...and the gates of Hades shall not overpower it." The implication is that gates are defensive, not offensive. The church should be the offensive party, not trying to withstand Satan's attacks. Light invades darkness, not the other way around.
Just some thoughts. I haven't completely processed all of them yet, but I think they're good to mull over...
