Free tickets to Kanye West's Sunday Service at Lakewood Church are being scalped for hundreds of dollars.

The concert at the church - lead by Joel Osteen - in Houston, Texas, is expected to draw “huge crowds”.

Several Twitter accounts have been promoting and selling tickets to the event, but a spokesperson from Lakewood Church told The Christian Post that the tickets are free and won't be available to the general public until 10 a.m. Saturday through Ticketmaster.

"Anything other than Ticketmaster would be fraudulent," the spokesperson says.

Lakewood church members are getting a chance to pre-order their tickets with a promo code. The number of seats available to church members is approximately under 17,000.

The concert is expected to begin at 7 p.m. but the doors to the church will open at 5:30 p.m. while concertgoers can start lining up at 4 p.m

Before Osteen's regularly-scheduled sermon, West is expected to share his conversion testimony at the 11 a.m. service.

The Lakewood spokesperson says both Osteen and his wife, Victoria, are excited about what God has been doing through West.

“We’re excited. It’s really neat to see what God is doing in Kanye’s life. Joel is very excited, Joel and Victoria. It will be a fantastic weekend,” the spokesperson says.

“It’s going to bring a lot of people who have never been to Lakewood as well. Kanye has a big influence on the culture.”
