Wayne co-wrote this song with Brett Beavers and Tony Martin. He told Roughstock: "I feel like my strengths are in song ideas. I write a lot. I've been keeping a journal since I was 12 or 13. I have lists and lists of song ideas. Brett Beavers had this melody. I went through my song list and said, "I have a title that fits that. It's called 'Just Knowing You Love Me.'" I sang it, and it was the perfect marriage. It was amazing how well it fit. Brett and Tony Martin have both proven that they can write hit songs. It was Tony who said 'Jimmy, this is a hit."

Wayne told AOL's The Boot: "It's a song about dealing with the world and the ups and downs and the fact that just knowing that person is there... just knowing you love me helps me get through all this stuff. I think it's a song people could relate to."

Wayne told the story of the song in an interview with The Boot: "I was in my driveway back home in Nashville. I was standing there pondering a thought about my friends and my family and just being very thankful for the things that I have in my life. I was thinking if everything just went away, those are the folks who are still going to be there at the end of the day. When you're down on your luck, those really, really good friends, good business partners and good family members are going to be there at the end of the day. That's where the idea 'Just Knowing You Love Me' came from. I had written it down in my journal. That was the first place I found that I could write it down.I was in the room with Tony Martin and Brett Beavers a different day writing with them. We were looking for a song title that would fit this melody that Brett came up with. His melody worked really well with 'just knowing you love me.' The syllables matched up perfectly with the melody that he had brought in.We all agreed that it was a song title that every single person in the world can relate to. It's a pretty simple song, and I just love that title."
