I've seen evidence - in my life and in other believers' lives, that when one is expecting the soon coming of Christ, their ministry increases many times over.
Most of the believers I know that think His coming is far off and/or they're not worried about it, their witnessing zeal and outreach is pretty weak.
Let's face it - the apostles were looking for Christ's appearing...after all, nobody really knows. But we have signs now that tell us that it's so close. And while I'm not screaming "the sky is falling", my anticipation for the Lord's return is a major part of what fuels my devotion to Him (and got me convinced that He was who He said He is).
