"Finally Home," like previous MercyMe songs, such as their Billboard Hot 100 hit "I Can Only Imagine" and "Homesick," is about frontman Bart Millard
's father who passed away. He explained to Christianity Today
magazine the background to the song: "I've been wanting for a long time to write a song that was sort of a closure for 'Imagine,' but I didn't want it to be a sappy piano ballad. When we were in the studio, the guys started playing music that had this Train kind of vibe - it was the kind of thing my dad listened to. As soon as they started playing it, I started writing down the first lines, 'I'm gonna wrap my arms around my daddy's neck and tell him that I missed him.' Then I ran in to the studio and started singing it. That song was literally written within five minutes from beginning to end. We breezed through it.
I remember singing the first two lines and just bawling. Then the guys were bawling. And Brown (producer Brown Bannister) was bawling because he had lost his dad about five years ago. At the time, I didn't think it should go on the record because I never wanted to be accused of aiming for the heart just to get a reaction. Brown was like, 'Are you kidding me? You made a grown man cry. This song is going on the record. I don't care what you think.' It's just one of those moments where the lyrics and the music seem to fit perfectly."
