Throughout the years, she has witnessed Ian eat and talk again, though his speech is still very limited. And earlier this summer, Ian underwent leg surgery to improve his walking. Each milestone calls for a celebration and has made the pair closer.
However those happy days come with a price.
"On my really hard days, I'm just so tired of the brain injury and I just want it gone but there is nothing Ian or I can do within ourselves to make that happen," she admits. "On those days, I sometimes get so angry and I'll get frustrated even though I know there's nothing he can do."
Despite his limitations, Ian is normal in many ways as he likes to paint, laugh with Larissa and spend quality time with her.
"One of the greatest gifts that he gives me as a husband is that he always wants to be with me. We could just be sitting on the couch together and he's just the happiest person in the world. He also always requests sweet bread, so if I make him sweet bread, he's always happier. He's so pleasant to be with. It's harder for him to initiate so he talks less but when he does, it's golden," Larissa shares.
While Larissa's role as a wife is anything but normal, she says she finds time to have a moment to herself or to be surrounded by family as her "fun" outlets.
"Nothing makes me happier than being with our nieces and nephews, spending time with them is just so fun. But sometimes I'll tell Ian that I just want an hour to either read. But honestly, cleaning is an outlet too because its gives me something to put back in order, it's a very controllable thing," she says.
She notes that she and Ian would like to have children someday though she does not know how many they would be able to manage, but they want at least one.
Since 2006, much has changed for better or worst in their lives but when she thinks about it, Larissa says she can barely imagine what life would be like if Ian had not been injured.
"I think he would be a film maker at the company that he and his best friend had started (before the accident) and we probably wouldn't be living where we are. I would probably have a lot more energy!" she exclaims.
Now that their love story, which garnered international attention in 2012 when John Piper's Desiring God website featured a video of their lives, is in print, Larissa says her hope for the future is simply to help others.
"It's crazy how God puts impressions in our hearts. I've always journaled but when I started writing the book and I would look back at some of my entries, I'd write 'I feel like my life is going to be very public,'" she says. "I always wanted to write a book but I never knew what my story was."
She adds, "We would love our story to help people in similar situations and help people love God more by seeing Him through Ian's story. We want to keep making sacrifices, we don't want to have a comfortable life; we want to do God's work, whatever the cost."
Eight Twenty Eight: When Love Didn't Give Up will be released on Aug. 28, which marks the Murphy's wedding anniversary and the anniversary of Steve's birthday.
