Speaking of the songwriting process, the grieving parent said, “It’s extremely therapeutic, it’s like talking about myself, it’s very difficult but it’s also a wonderful thing. Just like the song, he’s not physically here but he’s still very present in our lives.”

Shelton, 43, also spoke about the impact of Morgan’s song after surprising his friend during his interview with Clarkson.

“It’s easy to connect that song to anything that’s happened in your own life. But because Craig has been a friend of mine for so long, and Gwen [Stefani] and I were actually at the funeral,”The Voicecoach said. “It was his story and it hit me that hard just knowing him and the horrible tragedy, I can’t even imagine. It’s such a great, great song. And he had sent it to me.”

On Sunday, Morgan released a new music video for the single, which was filmed in the loft at his family’s The Gallery at Morgan Farms in downtown Dickson, Tennessee, according toCMT.

Morgan added, “Its simplicity embraces the truth of the lyrics of the song. I hope this video lifts people up. For anyone who has experienced loss, I want this song to give them the desire to pursue their faith and to have hope.”

In September, Morganspoke with PEOPLEabout the song and the death of his son. “It’s still difficult. I mean, Jerry is the first thing I think about when I wake up and the last thing I think about when I fall asleep,” he said.

“There are times when I am angry and I don’t understand it, and then there are times that I am joyous that we had him for 19 years. You have to let those joyous moments steer you away from the anger. I pray about it all the time. I don’t understand it and I probably never will until I get to heaven,” he shared.
