Nathan Fellingham in an interview with Adrian Warnock:
I think There is a Day is probably one I’d go back to. I was reading a book called The Discipline of Grace by Jerry Bridges. It’s not really a book about the second coming and our future in heaven, or anything like that, but there was obviously something that he put in there, a page that I read—that chorus literally just descended on me like—instantly. I can’t put it in any other way. It was like I got so excited by reading what I was reading... the chorus, “We will meet him in the air and we will be like him, and we will see him as he is . . .” and then that “Oh yeah!”—it was just genuinely what was in my heart. I remember I was in my bedroom. I slammed my fist down on the bed. That was genuinely what it was—it was like, “Oh YEAH!!” It so gripped me—so just from there I kind of started looking up some simple passages and, you know, I did the whole kind of following Scripture links to this one, and I’d follow it through my Bible and just came up with various lines, and really felt God’s grace in putting it together. A lot of people said to me, “It’s a great theological song.” You have some guys who really do know their stuff theologically, and it’s like, “Yeah, it’s just God’s grace!” I mean, in a sense, it’s just the Bible put to music.Which is one of the reasons I'm glad we give this to Relay to read over the summer before they begin their year of discipleship training in a student context, a year that is all about grace.
