In Hard Believer the artist is speaking to the love of their life, who is in denial of their feelings.
I think part of this song echoes how God feels towards His church. We were made for each other, Won’t you believe me now? Ephesians 5:25-33 (http://bit.ly/2zugtDA) uses husband/wife imagery to show the desired relationship between the global church and Christ. Just as a wife and husband should love each other whole heartedly, we too, are to live to show whole-hearted love to Christ.
Jesus and I were made for each other. How will this be the sound track of your day today?
