But he's crowdfunding the bill because God told him to, he says.
As the televangelist who preaches the controversial "prosperity gospel" explained to his followers in a video last week, if Jesus Christ walked the earth today, "he wouldn't be riding a donkey". "Think about that for a minute", Duplantis said.
Moreover, Copeland's television program "Believer's Voice of Victory", held a segment with Duplantis to discuss the difference between commercial airplanes and a private jets to spread the gospel.
The three-engine plane Duplantis has his heart set on is capable of carrying up to 12 passengers, can fly at speeds of up to 700 miles per hour, and boasts an impressive max range of approximately 6,000 miles.
Duplantis shows pictures of the three planes, which he describes as a Cessna Citation 500, an IAI Westwind II and a Dassault Falcon 50 purchased in 2006.
Nowhere was that more evident than the official Facebook page for the Destrehan based preacher.
By flying in the new plane, Duplantis says it will save money and not pay for "those exorbitant prices with jet fuel all over the world".
The reason why Jesse Duplantis wants the $54 million jet is as astonishing as the idea of a church minister having his private ride - because it requires fewer stops for refueling.
"So pray about becoming a partner toward it, if you like to and if you don't, you don't have to, but I wish you would", he said. "Yes, but I can't go in one stop. What I'm believing God for". "I'm interested in preaching the Gospel of the Lord Jesus Christ". "We can talk to God", Copeland said at the time.
CNN has reached out to Duplantis for comment.
He wouldn't live long enough to get to everywhere he needed by using cars, trains or ships.
He and Duplantis defended their use of private jets in a widely shared - and mocked - YouTube video. You can't, you can't manage that today. This dope-filled world - and get in a long tube with a bunch of demons. It's gonna change lives, one soul at a time.
