Nikola Tesla had a great respect for the Bible and Christianity. His mother taught him that all truth came from the Bible and his father was an Orthodox priest. There is no doubt God used him to help usher in the 20th and 21st centuries with his amazing inventions. As you read the quote and listen to the video below, you will see how a man, focused on science alone, can come so close to Ultimate Truth, yet miss the Ultimate Answer.
Was Tesla a Christian? There is no strong evidence for it. Tesla died alone and broke on January 7, 1943 at the age of 86. His body wasn't discovered until two days later by the maid who ignored the "Do Not Disturb" sign on his New Yorker Hotel room.
God could have dealt with Nikola in his last hours. A dying man, some say, often returns to his childhood memories and will contemplate his relationship with God when he knows he will meet Him soon. Nikola Tesla read the Bible. One of his inventions was based on an idea he received while reading the book of Revelation. Maybe some of God's Truth got hold of him before he left.
