The 36-year-old from New South Wales, who beat fellow finalist Michael Weldon in a three-part challenge to be crowned the winner of the cooking reality television show on Sunday night, said that she didn't want to be too "corny".
Bracks told Dave Hughes on his radio show: "[I considered mentioning God] but then I thought, everyone then goes, 'Oh great, it just sounds like the Logies.' It sounds corny and that is not the type of Christian I am."
She also said despite the fact that she is "always talking to God", she didn't "actually pray" to help her win MasterChef because she thinks that God probably has better things to do.
Bracks continued: "I would say that I believe what the Bible says and I try to live that way, so that it's about trying to have a relationship with God and not about the things you do or don't do."
She also revealed that she "might give herself a day off" after filming, but that she has to meet with editors and printers to discuss her cookbook and wants to get started right away.
Bracks caused controversy on MasterChef when she refused to address Buddhist leader the Dalai Lama as "Your Holiness". She said: "My belief is that God is the only one that is perfectly holy. So in terms of everybody calling him Your Holiness, that was probably the only aspect of the challenge I was uncomfortable with."
