Writing in Lena Dunham and Jenni Konner's Lenny Letter, she said: "I feel that I kept the serious vows I made in front of God with every inch of my heart, which is why I am still honouring them today even though my relationship with my ex-husband is in a different place.
"I believe in caring for my partner - past or present - 'in sickness and in health,' and feel at peace with my relationship with God even after the fact. I'm thankful that I can rely on my God, who, along with my family, has led me through some of the most difficult times of my life."
Khloe also revealed that her spirituality helped her through the death of her father, Robert Kardashian, when she was just 19.
She said: "After he passed, I was bitter and angry - I was VERY angry at God. I didn't understand why someone who was so great, my dad - why he would be taken away. My dad was such a believer, so I couldn't come to terms with how someone with such a deep relationship with God could be gone.
"I was young and I needed someone to blame for what had happened. But then I started to process the end of my father's life, and it changed something inside me."
