"He moved countries, he was that scared about the whole religious thing because he was brought up in the church. My friends and I were like, 'Dude, why did you leave, what did you think we would say?' It became not a big deal at all," he told news.com.au.
He describes his view towards religion as one that focuses on the God of love, and not focusing on Christianity being the one and only way.
"I don't think anyone has the right to say what they believe is more important or more significant."
"I still believe in God, I still believe in the fundamentals of that. But I base it on the fact God is love. I don't feel God is what people have said He is throughout generations. For me it's a faith. People sometimes lose the concept of faith. I don't know if there's only one God, I don't know if there's a God, I just have a faith that there is. That's what I've grown up with. But the minute it starts to become about hate, I switch off."
In his latest album Armageddon, his new song 'Get Along' expresses his hope towards interreligious harmony, with the verse: "When all the worlds collide, all they know is to divide, and it's easier if they're faceless to hate the other side, and the others caught between, are the only ones to bleed" and the chorus: "Dear God, dear soul, dear Mary, Mohammed, can we all just get along?"
Sebastian has told the Daily Telegraph that this is the song that he's most proud of writing, and will get attention. It will also be his next single from the sixth album.
Guy Sebastian attended and was a lead singer in Paradise Community Church's youth conference Planetshakers when he won the Australian Idol in November 2003, and since then was regarded by many as the poster boy for Christianity.
