Singers Mariah Peters and Joel Smallbone of for King & Country have become a staple couple in contemporary Christian music for several years now, but during her second installment of "I Am Second" the bride admitted that it's been a battle.

Peters first appeared in the white chair film production six years ago after Smallbone had proposed. The then 20-year-old, spoke of her music and faith. She described being on American Idol auditioning for the judges and choosing to trust in God after they cut her. Peters showed off her engagement ring and was ecstatic to start the next chapter of her life as a wife.

"I feel like the 'I Am Second' interview really kicked off this new chapter in my life where I had this forever partner," Peters can be heard saying in the Second Edition taping. "I was able to partner with my husband and step into music. I don't think we were quite prepared for reality to sink in."

Smallbone joined the filming as Peters talked about their love story and after he shared from his perspective things became more serious. Along with navigating their careers and letting someone else into their most intimate space, the couple admitted they learned that the lines are very thin between hate, hurt and love.
