The widow of "American Sniper" author Chris Kyle shared a touching tribute to him on Facebook on Valentine's Day.

The message came just days after Taya gave an emotional testimony in the trial of her husband's killer, Eddie Ray Routh. 

"We all suffer," she wrote. "It's part of life. The blessing is – while evil exists, Divinity does too and it is stronger. 

"This weekend, I feel blessed to know that I will see Chris again someday," she continued. "I feel blessed I had the opportunity to be his wife, to learn from him and love him. I feel blessed to know the support of many and the ignorance of few." 

Kyle held the distinction of being the most lethal sniper in US history, with 160 confirmed kills as a Navy SEAL. He wrote about his experience in the military in the 2012 memoir "American Sniper," which was turned into a blockbuster film by Clint Eastwood this year. 

In February 2013, the 38-year-old husband and father of two was shot to death at a shooting range in Texas by Routh, a military veteran allegedly suffering from psychological problems. Kyle' s friend, Chad Littlefield, was also killed. 

Despite her tragic loss, Taya said she is "working on finding peace and joy" in life without her husband. 

"My heart may be broken and my spirit tired, but today I thank God for sending my Valentine when I needed him the most," she said.

"I thank God for the time we had, the children we share, the promise of seeing each other again, and the friends and family who stay with me today. I am forever changed and forever grateful."
