John Allen Chau, an American missionary, embarked on a journey to North Sentinel Island with the purpose of proselytizing the indigenous population to Christianity.

The isolated Sentinelese people reside on a small island in the Indian Ocean, approximately the same size as Manhattan Island in New York.

The land has the potential to sustain a population of 80 to 150 individuals without difficulty, but the actual number of inhabitants could range from as low as 15 to as high as 500.

In 2018, the individual, who was 27 years old at the time, enlisted the help of a fisherman to travel to the island. Raised in a Christian household in Vancouver, Washington, he possessed a fervor for hiking, camping, and exploring different parts of the world.

During his high school years, Chau acquired knowledge about the Sentinelese, a group of hunter-gatherers who inhabit the island and zealously safeguard their territory against intruders.

Although he was well aware of the tremendous hazards posed by the island, he proceeded to venture there in November of the same year with the objective of proclaiming the gospel of Jesus to the islanders.

Upon arrival, he documented his purpose as "doing this to establish the kingdom of Jesus on the island... Do not blame the natives if I am killed."

"You guys might think I'm crazy in all this but I think it's worth it to declare Jesus to these people," he wrote in the letter to his parents.

"Please do not be angry at them or at God if I get killed."

"Rather please live your lives in obedience to whatever he has called you to and I'll see you again when you pass through the veil. This is not a pointless thing - the eternal lives of this tribe is at hand and I can't wait to see them around the throne of God worshiping in their own language as Revelations 7:9-10 states."

"I love you all and I pray none of you love anything in this world more than Jesus Christ."

Chau also wrote in his diary: "I hollered: 'My name is John, I love you and Jesus loves you'."

"I regret I began to panic slightly as I saw them string arrows in their bows. I picked up the fish and threw it towards them. They kept coming."

"I paddled like I never have in my life back to the boat."

Regrettably, following his arrival on the island, it is believed that he was struck and killed by arrows.

A police statement explained: "The fishermen saw a dead person being buried at the shore which from the silhouette of the body, clothing and circumstances appeared to be the body of John Allen Chau."

In a statement, Chau's family said: "We recently learned from an unconfirmed report that John Allen Chau was reported killed in India while reaching out to members of the Sentinelese Tribe in the Andaman Islands.

"He loved God, life, helping those in need and had nothing but love for the Sentinelese people.

"We forgive those reportedly responsible for his death. We also ask for the release of those friends he had in the Andaman Islands."
