A musician who spent years writing songs and performing with the globally influential Christian music collective Hillsong now says he is questioning his faith.

Marty Sampson is a songwriter and worship leader for the recording label that grew out of Hillsong Church, a congregation based in Sydney that now has branches in 23 countries. Hillsong frequently sets the trends in the Christian contemporary music industry, and its songs are sung by millions of people around the globe every Sunday.

Sampson has been writing for Hillsong since at least 1998 . More recently, he was one of the musicians behind The Lords Prayer, a song that appears in Hillsong Worships 2018 album, There Is More. The song is a musical rendition of Christianitys foundational prayer.

But Sampson now appears to be questioning the foundations of his faith. In mid-August, he started sharing his doubts about Christianity with his followers on Instagram. According to the faith-based news website Christian Post, Sampson announced in a since-deleted post that he was genuinely losing my faith , clarifying later that while he hasnt completely renounced Christianity, his faith has been on incredibly shaky ground.
