The Christian missionary who was killed trying to convert a remote island tribe in India wrote in his diary that he was entering "Satan's last stronghold," the Washington Post reports.

John Chau wrote that he knew he might be killed by the tribe, which aggressively shuns the outside world and which is protected from incursion by Indian law.

“I’m scared,” Chau wrote. “Watching the sunset and it’s beautiful — crying a bit … wondering if it will be the last sunset I see... Lord, is this island Satan’s last stronghold where none have heard or even had the chance to hear your name?”

Chau, 26, was from the Portland suburb of Vancouver, Washington and an adventurer seeker who also proselytized to remote tribes.

His diary was provided to the Post by his mother.

"Chau’s diary reveals a portrait of a young man obsessed with the idea of bringing Christianity to the Sentinelese," the report reads. "It also shows that Chau knew his mission was illegal. He wrote of maneuvering to avoid the Indian authorities who patrol the waters near the island."

“God Himself was hiding us from the Coast Guard and many patrols,” he said before his fatal journey.
