WATCH: How Mary Lambert Lost and Found Her Faith

Given that, as singer Mary Lambert tells it, her mother came out as gay and her own father sexually abused her, it's understandable that Lambert might have had some issues growing up in the Pentecostal faith.

"My faith was Pentecostal and we were shunned from the church -- we were ostracized," said Lambert, in the interview with bisexual Christian journalist Eliel Cruz.

"I had faked it for so long," Lambert told Cruz, who said she went from hating Christians and the church to rediscovering her evangelical faith in high school. "I think faith and God and the universe expresses itself in each of us differently."

Lambert also addressed the perception that you cannot be both Christian and LGBT. "We keep separating the LGBT community, apart from the Christian community, because there's this divide. ... It's so silly to me, the bible's not meant to be divisive."

Cruz asked her if reparative therapy inspired the lyric "I can't change" in her song "She Keeps Me Warm."

"That's absolutely it. But I never went through Exodus or anything like that," said Lambert, who added that she did come to a crisis point at age 17 when she realized "apologizing" every day for being gay was not right.
