I agree that all of life is spiritual. You can’t separate life in Christ to part is and part isn’t. We can, however, live our lives as if we weren’t in Christ, which is a sad thing. Many times, I see that in my own life. I guess it boils down to 1 Cor 10:31. Am I doing what I’m doing for the glory of God or for my own glory? That, I believe, is my point and my struggle. Am I doing this book for the glory of God or my own glory?
