Joel Osteen's still going big with his Easter service amid the coronavirus pandemic, but of course -- for safety purposes -- all the big names he's recruited will be performing remotely ... for a virtual service.

Sources close to Osteen tell TMZ ... his Lakewood Church in Houston will welcome Kanye West, Mariah Carey and Tyler Perry on Easter Sunday to deliver messages of love and support to his massive audience.

Our sources say Mariah will be part of a special tribute to medical professionals and first responders putting their lives on the line in the battle against COVID-19. We're told she's going to sing her song "Hero" via webcam.
