New York Times and USA Today bestselling author and pastor Judah Smith is set to release his latest book "Life Is_____: God's Illogical Love Will Change Your Existence" on March 3.

The much anticipated book is a follow up to his 2013 release "Jesus Is ____," which encourages readers to complete the sentence through reflection and understanding who and what Jesus Christ is in their own existence, and helping them relate to each one of the characteristics of Jesus Christ.

In "Life Is _____," Smith will explore the possibilities open to readers while completing the sentence.

Smith's website explains that the book seeks to inspire readers to love and be loved, enjoy God to the fullest, trust God and be at peace with God, themselves and with others.

Smith is the lead pastor of the City Church in Seattle, and is popular among the young faithful because of his wit, humour and unique style of bringing the flock closer to God.

He is also a close friend and mentor of Canadian pop phenomenon Justin Bieber, who has in the past tweeted direct messages to Smith about faith and his sermons.

"Blessed to hear one of the best@judahsmith speak today about our Lord in church today. #JesusIs" was one of the posts shared by the artist, to which he replied simply: "love you"

Pop singer Selena Gomez, who was also romantically linked to Justin Bieber was also seen attending one of Smith's Jesus Is ___ events while the pastor was on tour.

Radar Online quoted one of the audience, Taylor Pike saying: "She smiled at us, probably because we were going crazy worshipping God. She looked very happy to be there. You don't see young celebrities at a church conference often!"

Audience members also said that they saw Gomez tearing up as she prayed with the crowd in the jam packed venue.
