I agree with Joel also, and I know we here hold to the same view of:
Even though we know what is coming, we don't just sit on our hands, or encourage anyone else to either and do nothing. We can still make a difference in this world and the people around us. We don't let evil just run rampant, we are asked to occupy until Jesus comes.
It is kinda like the saying about believing that Jesus is coming now but live as if it is a hundred years away. I hope that makes sense.
I hope that doesn't sound too preachy.
