A source close to the Sorry singer told The Sun why the Christian musician hasn't released an album for more than two years.
"Justin is on the lookout for songs which really reflect where he is in his life in terms of spirituality," the unnamed source said.
"He has always been religious but the last two years have seen him grow closer to the Hillsong Church and it has changed his entire life. He has a totally different outlook now.
"After he finished his last tour he really wasn't interested in recording any music for a while."
The Canadian star's pause from music followed an arrest for throwing eggs at a neighbour's home and driving under the influence of alcohol.
He has since been photographed numerous times attending Hillsong Church New York and with its pastor Carl Lentz who baptised him.
The fifth studio album is reportedly not going to be released until as late as 2019.
