MONROVIA, Liberia — It decimated hospitals, schools, families, fortunes and, for many, even their faith.

Now, it is officially over. The Ebola outbreak has ended in Liberia, the World Health Organization announced Saturday, an enormous milestone that seemed impossibly far off last year when dead bodies blocked roads and the sick prayed for ambulances that never came.

Desperately, the country is trying to rebuild just about everything, from its health and education systems to its economy and international image.

But in the dim hall of the United God Is Our Light Church, its generator turned off to shave costs, the congregation has been trying to repair something more fundamental: its spirit.

“Some of you are thinking that this church will die,” the church secretary, Joseph Vayombo, recently shouted in the small Pentecostal church here, no longer able to contain his frustration at all the empty seats around him. “There are people here who want this church to die.”
