Theologians tell a story to illustrate how Christ has triumphed and the war is all but over: Imagine a city under siege. The enemy that surrounds the city will not let anyone or anything leave. Supplies are running low, and the citizens are fearful. But in the dark of the night, a spy sneaks through the enemy lines. He has rushed to the city to tell the people that in another place the main enemy force has been defeated; the leaders have already surrendered. The people do not need to be afraid. It is only a matter of time until the besieging troops receive the news and lay down their weapons.
Similarly, we may seem now to be surrounded by the forces of evil disease, injustice, oppression, death. But the enemy has actually been defeated at Calvary. Things are not the way they seem to be. It is only a matter of time until it becomes clear to all that the battle is really over.
