Pastor Tran Dinh “Paul” Ai, former witch doctor turned Pastor

As a teenager he left the hopelessness 

of Buddhism for the power of black 

magic, then American missionaries 

demonstrated the amazing power of 

the God they served, which made his 

3,300 gods seem impotent. After 

receiving Christ, he entered into a new 

battle with communist authorities for 

the soul of the Vietnamese people — 

battle still raging today.

“I grew up in a very strong Buddhist 

family,” says Pastor Tran Dinh “Paul” 

Ai, founder of Vision Outreach 

International Ministries. “I was sent to 

a Buddhist temple and trained to be a 

Buddhist monk,” he says. “My father 

was a very successful Chinese medical 

doctor, but he was bothered by 

politicians who tried to extort money 

from him.”

“He vowed if he had a son he would 

send him to the temple so he could be 

trained as a monk,” Ai says. “My name 

in Vietnamese means ‘Stop loving the 

world.’”

At age 15, after only a year of study, he 

became disenchanted with the 

“hopelessness of Buddhist doctrines.”

Seeking a more powerful religious 

experience, he journeyed to the dark 

side. “I went to study black magic and 

became a witchcraft doctor, serving 

3,366 gods,” Ai says. “They gave me 

power, but they made me bow my life 

to their strongholds,” he says. “They 

also made me hate the gospel.”

In 1970, as President Nixon sent 

American troops into Cambodia from 

Vietnam, causing mounting protests 

on U.S. college campuses, American 

missionaries entered Ai’s town in South 

Vietnam. “A lot of people in my town 

went to the crusades and met the 

Lord,” Ai says. “Some of my black 

magic students came to me and said, 

‘Master, you must stop this crusade, 

otherwise we will lose all our 

customers in this town,” he recalls. 

“So I went to the crusade the 

following day to check it out.”

Ai expected to find the missionaries 

performing “religious activities,” but 

was surprised to find them singing 

songs, reading the Bible, and giving a 

simple message. “They said, ‘We don’t 

want to bring to Vietnam a new 

religion, because all religions will make 

you more and more burdened. But 

Jesus promised if you bring your heavy 

burdens to him he will give you rest.’”

Opposing American missionaries

This message was grating to Ai, and he 

frantically sought some way to stymie 

their efforts, afraid the townspeople 

would no longer need his services. To 

his chagrin, many in the area were 

being saved, and offering testimonies 

of answered prayers.

Ai turned to his demonic hosts. “I 

called up 1,000 gods at that first night, 

but at the end of the service I realized 

my gods were not showing up to do 

their job,” he says. “The next evening I 

called up 2,000 gods, but nothing 

happened.” He went home to fast 

and pray to his 3,366 gods.

“I said you have to wake up and show up and shut down this crusade,” Ai says. ‘I prayed to all 3,366 but none of them showed up,” he says.

Suddenly a dawning realization swept 

through his mind. “I realized that 

Buddha was a good man who was 

wise, but Buddha died. He never 

promised to save anybody or help 

anybody,” he says. “Then I realized 

Jesus Christ is different. He is not only 

good and wise, he rose and he’s alive!” 

At that moment, as Ai recognized the 

futility of his previous religious path, 

he surrendered to Jesus Christ as his 

Lord and Savior.

“I gave my heart to the Lord, and God 

saved my life and set me free and 

called me into ministry,” Ai says. 

Shortly after this, ‘Tran Dinh’ received 

a new name. “After I got saved, they 

told me, ‘Brother Ai, there was a man 

in the Bible exactly like you. He was so 

religious and he hated the gospel and 

he persecuted the church. His name 

was Saul but finally God got a hold of 

his life and his name was changed to 

Paul.’”

Tran Dinh accepted their advice and 

took the name of Paul. “One month 

later when I read through the Bible I 

said, ‘Uh-oh, they gave me the wrong 

name. Paul is a man who went to 

prison after prison, and I don’t want to 

be in prison like Paul.’”

Despite his misgivings, the new name 

stuck. “I was resented by the 

community and I was disowned by my 

family, but the church accepted me 

and discipled me,” he says. Ai’s family 

forced him to move out of their home.

Looking back, Ai is thankful his family 

kicked him out, because this provided 

the impetus for him to attend Bible 

school. In April 1975, only two days 

before the U.S. evacuated Saigon and 

the entire nation fell to the 

communists, Pastor Ai was ordained.

Fleeing the communists

Pastor Ai’s immediate impulse after 

the fall of Saigon was to join the flood 

of his compatriots fleeing the 

communists by any means possible. 

“All our leadership got together to 

seek the Lord, and they decided we 

had better get out of the country 

before the communists threw us in 

prison,” he says. “So we all decided to 

leave and got on a boat.”

“But when I got on the boat the Holy 

Spirit spoke to me and said, ‘What are 

you doing on this boat? Stop loving 

the world. Do you want to be a Jonah?’

“It was strong enough to scare me,” 

Pastor Ai recalls. His friends on the 

boat noticed Ai was sweating 

profusely.

“Brother Ai, what happened to you?” 

they asked.

“I just heard a word from the Lord,” he 

told them.

“We need a word from the Lord 

because we’re about to make a very 

dangerous journey on the ocean,” 

they said.

“God just asked me if I want to be the 

Jonah of this boat.”

“What?” they cried in unison. “Get out 

of the boat—we don’t want to have 

Jonah with us.”

Pastor Ai was forced off the boat. “I 

was so stupid, I thought, I shouldn’t 

have told them that.” Unsure of what 

to expect, he made his way back to 

his church. “The following day I was 

arrested by the communists and sent 

to a forced labour camp,” Ai recalls.

He would spend more than ten years in 

these camps as the communists 

attempted to reeducate him. 

“Communism is a religion,” he says. 

“They compete with other religions.”

“It was terrible,” Ai says. “I tell 

Americans you don’t have prisons here 

in America, you have free hotels,” he 

says. “In America the prisons have air 

conditioning, heat, internet access 

and cable TV.

“In Vietnam there was nothing like this,

” Ai says. “I slept on a floor that was 

either dirt or cement,” he says. 

“Sometimes they don’t give you food 

to eat so I have to go out in the jungle 

to find leaves to eat.” Ai and his fellow 

prisoners worked 10-12 hour 

days doing backbreaking agricultural 

work: harvesting potatoes, cashew 

nuts, and rubber plants.

During his first five-year term he had 

no toothbrush, soap, or other personal 

items. “After I was released from 

prison, I packed a bag with a 

toothbrush, soap, towel, and 

underwear in it for the next time that 

the police came to arrest me. I carried 

this bag with me everywhere I went, 

and it stayed next to me when I slept 

at night.”

Despite persecution by the authorities, 

Ai continued his efforts to plant house 

churches, planting 24 new churches 

from 1988 to 1990. One day he was 

picked up by the authorities and 

brought to the police station, where he 

was warned to stop planting churches. 

In 1980 he was released from his first 

of eight terms in prison, and married 

Ruth Kim-Lan, a former high school 

teacher. She became disenchanted 

with teaching after the communists 

“tried to change the children’s minds 

from believing in creation to evolution.” 

She felt called to ministry so she could 

“teach the children about God and 

his creation.”

Ai considered their threats carefully, 

but tried to explain he had received a 

calling from God. “The water buffalo 

was made to plow the field,” he said, 

“the horse was made to pull the cart, 

and the preacher was made to preach 

the Gospel.”

His reply made them burn. “If you will 

not stop, you will be back in these 

camps,” they warned.

“You do your job and I’ll do mine,” 

Pastor Ai replied. About a month later, 

Ai was followed by the police and 

arrested as he reached his home. He 

was sent back to prison, but this time 

he had the backpack with him 

containing his personal effects.

His backpack did not remain intact for 

long. “In prison the guards cut the 

straps, a standard practice because of 

fear of hanging,” Ai recalls. “There was 

a wild man in the prison they called 

‘Scissor.’ He was a tailor and he carried 

scissors with him all the time as a 

weapon. He killed many people both 

in and out of prison.

“Everyone in prison was afraid of him, 

including the guards,” he adds. “He 

used metal cans and cut the metal to 

make himself a breastplate to keep 

people from stabbing him to death.”

But Pastor Ai began to pray that God 

would soften this desperate man. “I 

began to share the love of Jesus with 

him and told him how Jesus would give 

him peace and be his friend,” Ai recalls. 

“As I continued to show him friendship 

and God’s grace, he gave his heart to 

the Lord.”

“As an expression of gratitude, he used 

one of his shirts to fix my backpack 

and make me a hat for protection 

from the sun,” Ai says, knowing he 

was violating camp rules.

“If the police ask you where you got 

these,” Scissor told him, “just tell them 

they are from me and you will be safe.”

Pastor Ai had found an unusual 

guardian in the camp. “The Lord used 

Scissor to provide for me not only my 

backpack and hat but also protection 

and many other things I needed in 

prison.”

“The authorities thought if they put him 

in prison, the church would stop 

growing and be destroyed,” writes 

Johnny Thinh, a friend and co-laborer 

of Pastor Ai’s. “But they were wrong, 

because Jesus himself is still the head 

of the church, and even the gates of 

hell shall not prevail against His church.

“Wherever they moved Pastor Paul Ai, 

new churches appeared,” he adds. By 

the end of 1997, Pastor Ai’s 

denomination had over 15,000 

members in 175 congregations, all of 

them home churches, based on the 

cell group system Pastor Ai learned 

from studying church growth in Korea, 

China and other nations, according 

to Thinh.

In 1999,Pastor Ai was arrested in Hanoi 

and sentenced to a five-year term. 

“They tried to kill me, but God used a 

former State Department official, 

acting as an ambassador-at-large, 

along with pressure from the U.N., to 

win my release. They expelled me — 

kicked me out of the country,” he says. 

“I left by Christmas 1999.” 

Now Pastor Ai’s focus is on reaching 

Vietnamese expatriates in a host of 

countries. “There are 2.2 million living 

in the U.S. and almost 3.0 million living 

around the world,” he says. “I want to 

reach the Vietnamese overseas and 

disciple them so they can go back to 

bring the good news of Jesus Christ to 

their families and communities.”

“Some day God will open Vietnam just 

like He did in the Soviet Union,” Pastor 

Ai says. “The underground church is 

really growing. My job right now is to 

prepare and train disciples for that day.”

“We want to bring believers back to 

Vietnam—not with M16 rifles, but with 

John 3:16 Bibles,” he says.
