The drop box is attached to the side of a home in a ragged working-class neighborhood. It is lined with a soft pink and blue blanket, and has a bell that rings when the little door is opened.

Because this depository isnt for books, its for babies ? and not just any infants; these children are the unwanted ones, a burden many parents find too terrible to bear.

One is deaf, blind and paralyzed; another has a tiny misshapen head. Theres a baby with Down syndrome, another with cerebral palsy, still another who is quadriplegic, with permanent brain damage.

But to Pastor Lee Jong-rak, they are all perfect. And they have found a home here at the ad hoc orphanage he runs with his wife and small staff. It is the only private center for disabled children in South Korea.

"This is a facility for the protection of life," reads a hand-scrawled sign outside the drop box. "If you cant take care of your disabled babies, dont throw them away or leave them on the street. Bring them here."

Since 1998, Lee, now 57, has taken in nearly three dozen children ? raised them, loved them, sent them to school. He has changed their diapers, tended to their cries in the middle of the night. Today, he has 21 wards: the youngest a 2-month-old, the oldest 18.

His motivation is painfully personal. Twenty-five years ago, Lees wife, Chun-ja, gave birth to a baby so disfigured Lee kept the boy from her for a month until he could figure out a way to tell her the unthinkable, explaining only that the child had a serious illness and was rushed to another hospital.

The baby was born with cerebral palsy. A mammoth cyst on his head choked off the blood flow, slowly rendering him brain-damaged. Doctors gave him months to live.

Today he lies on a bed in Lees home, his legs splayed at impossible angles, his feet turned back inward. Eyeing the room impassively, he occasionally lets out a snort or sigh, as his parents regularly vacuum his saliva through a tracheal hole in his throat. They call him Eun-man, which means full of Gods grace.

He plays the role of emotional touchstone for an orphanage in peril: Health officials have ordered Lee to close his drop box, saying it encourages parents to abandon their babies.

Authorities say Lee has no formal training and not enough space for his wards, only two of whom are not handicapped; they were left by single mothers. Lee has no license, but for years he had operated underneath the radar. Now he worries he will lose the government funds he receives as the childrens legal guardian; the money keeps him in operation, along with donations from local firms and private benefactors.

Orphanage supporters say authorities are missing the big picture. Though there are other institutional facilities nationwide for disabled children, they say, no salaried caregiver could match Lees compassion and paternal touch.

"Rather than look at what he can bring, they focus on what he doesnt have," said Peter A. Dietrich, an orphanage volunteer. "The enormity of his mission hits you between the eyes. I dont know anyone who goes there for the first time and doesnt tear up."

Eun-mans birth caused a religious man to question his faith.

"I asked God, Why would you give me a handicapped child? I wasnt grateful for this baby," Lee recalled.

He soon came to regret those words. Looking down at his son, helpless and beyond hope, he says he witnessed the preciousness of life. He and his wife decided to work desperately to keep the boy alive.

In the mid-1980s, Lee said, the disabled in South Korea were often viewed as embarrassing curiosities ? more creature than child. Even today, he said, babies with physical deformities are seen as a national shame in a culture that prizes physical perfection, where cosmetic surgeries have become as common as haircuts.

Given his limited brain function, Eun-man needed constant care. He spent his first 14 years at a hospital. To help pay for his care, Lee sold his family food market, borrowed money and took up odd jobs to bring in more cash.

He spent months at the hospital and began visiting the rooms of other disabled children, encouraging their parents not to give up on them. Many began calling him "the pastor."

Strangely, the boy Lee once blamed on God ended up bringing him closer to his faith. In 1992, when Eun-man was 6, Lee entered theology school to become a Christian minister.

One day, an elderly woman at the hospital asked Lee to take her paralyzed granddaughter. The bargain: If Lee said yes, the woman said, she would agree to convert to Christianity. He accepted the child, named Sang-hee, who still lives with him. Months after making the deal, the woman was dead.

A social worker then asked Lee to accept the brain-damaged daughter of a 14-year-old girl who drank and did drugs during her pregnancy. The social worker assured Lee the infant, named Hannah, wouldnt live long.

Lee fed her through a tube, amazed at the childs hunger to survive. Hannah lived six more years: "When she died, I cried so much, more than even when my own parents passed away."

Thats when Lee vowed he would never turn away a challenged child. He has officially adopted several as his own and gained temporary legal guardianship of others.

In 2009, he installed the drop box. Immediately, the babies began appearing, some with their umbilical cords still attached.

The child welfare people visited Lee in spring. They had seen a TV report on his orphanage. The drop box had to go.

Child abandonment is a crime in South Korea and they said Lee provided parents an easy out. They said the orphans also deserved to know the identity of their biological parents eventually, a service Lee could not provide with the anonymous drop-offs.

Although they acknowledge Lee is well-meaning, officials believe he may be doing more harm than good. "Just accepting an infant without going through the proper verification steps is wrong," said Lee Woon-gyu, a child welfare officer.

Social workers who recently visited the orphanage say that 21 children are far too many for a four-bedroom home; some called the conditions unsanitary. They added that the law requires a doctor to be on hand round the clock in case of an emergency.

Pastor Lee insists that his orphanage has been running safely and efficiently, but acknowledges that he wants to raise the money to build a larger facility. He says the drop box offers salvation for babies who might otherwise be deserted in trash cans or public restrooms. He refused to remove the box, but agreed to turn over any children left there. Since February, eight infants have been placed there.

On a recent day, he hurried around the orphanage, kissing each baby on the cheek and forehead as four donated washing machines hummed in the background.

The walls are covered with pictures of his brood, some of whom are named for the time they appeared in the drop box, such as Midnight and Autumn. Of the 32 children he has taken in, three have died, three went back to live with their parents, and five were adopted.

Lee says he loves them all equally, but theres one he cannot forget. Little Hannah is buried under a tree just outside Lees front door. "I just couldnt let her go," he said. "It comforts me to know shes still here."
