The Holy Fire under thy buttocks
The people of God are not merely to mark time, waiting for God to step in and set right all that is wrong. Rather, they are to model the new heaven and new earth, and by so doing awaken longings for what God will someday bring to pass.
Quite a few Christians fixate on when Jesus is coming back. His Kingdom is here, the harvest is bountiful, and Jesus instructed us that even He doesn't know when He'll come back. We are to follow Christ daily and exemplify his love through our conversations, our relationships, our employment, and other interactions we have with the world.
How many of us are praying in the middle of the street, so willing to show everyone how pious we are, when we are instructed to go pray in a closet? How will the world know who we are? Through our love. Through the faith behind our actions.
Jesus changed the world despite two hostile governments claiming sovereignty over his ministry area - yet one by one, through his interactions, everyday people came to know Him as their Lord - and the world was changed forever.
