The title track of the album, I Will Sing, was written by Moen. It was written while Moen was in his car at one of Alabama's gulf coast beaches, trying to write songs for his upcoming album. He had been having a frustrating day, and the lyrics he wrote demonstrated his feelings. However, he did not like the lyrics. He said,
I didn't feel anything the entire day. It was one of those times when you wonder where God is. I was driving back home, feeling frustrated, and I said, "Lord, You seem so far away, a million miles or more it feels today." It just popped out. Then I got another line: "And though I haven't lost my faith, I must confess right now that it's hard for me to pray." The words kept coming, and I wrote the entire song right there in my car, but I didn't like it. I thought, "What a waste! I need songs for the album; I don't need this!"
Moen did not plan to use the song, thinking that he would "never put it on a Hosanna! Music album".
Later, he found out about the death of David C. Reilly's daughter. Reilly had been designing album covers for Integrity Music for more than a decade. Moen then recorded the song on a CD and sent it to David, with an encouragement. The note he attached to Reilly said,
I know you're going to have days when you feel like, "Where in the world is God?" but I want to encourage you to sing. Don't give up.
It was then that Moen discovered the value of the song, realising that God wanted his people to be "honest before the Lord".
