"Don't magnify your problems, magnify God," Joel Osteen told the crowd.
He went on to share his life story, starting from when he was a college student in Oklahoma, to the moment he met his wife Victoria at a jewellery shop in Houston, to when he gave his first "nervous" sermon at Lakewood Church.
Joel also gave a message about living a positive life in God's favour. "You need to see yourself the way you want to be," he encouraged the crowd.
"It's not enough to see it - you need to learn to say it."
He emphasised that we are children of the Most High God, and because of this, we must live favour-minded.
Victoria Osteen later took to the stage, urging the crowd to "encourage one another, starting with your mouth".
Joel and Victoria Osteen weren't the only ones who graced the stage. Joel's mother, Dodie Osteen, also came on to testify how God saved her from severe liver cancer in 1981, drawing loud cheers from the crowd. The Osteens' two children, Jonathan and Alexandra, also shared a Bible verse and sang on stage.
The Osteens kicked off their UK tour Tuesday at the Odyssey Arena Belfast in Northern Ireland and will speak at the NEC Arena in Birmingham tonight.
'A Night of Hope' featured praise, worship and prayer with electrifying music from Dove Award-winning Cindy Cruse Ratcliff and the Lakewood band and ensemble.
