Marquee Evangelism

So, I'm driving down Glenstone this morning, before I get to the McDonald's billboard, and I see the marquee for a local Baptist church (appropriately named Glenstone Baptist Church). The marquee says: "A vision with out a task is but a dream." Pardon me, but what the hell does that mean? Is it just me, or does that make no sense at all? I mean, I always thought vision and dream were pretty much synonymous. So I'm sitting here at my keyboard trying to figure out just exactly what that might mean, and the only thing that comes to my mind is what better things I can be doing.
