The letter was written by Strickland on the day of their wedding.
“The Lord is good always…I know this because in the the most heart aching moments, when it seems too difficult to bare, God knows just how to make me smile,” Helen Strickland wrote in the post.
Strickland, 29, and his friend Chase Morland, 22, were both reported missing on Dec. 27, 2015, while on a duck hunt at Kaw Lake in Kay County, Oklahoma.
Morland’s body was recovered the following day and the Backroad Anthem singer’s body was recovered by the Oklahoma Highway Patrol on Monday.
Helen recently attended Morland’s visitation.
“We had the opportunity to go to Chase Morland’s visitation tonight,” Helen wrote. “He was so loved by so many people. It was encouraging to be around his wonderful friends and family.”
Helen also noted that she brought Craig’s dog “Sam” to the visitation per the Morland family’s request.
“Sam was also invited,” wrote Helen. “He has truly been a comfort to all of us.”
