The song is about how the heart lags behind the head – i.e. the head sees the logic but the heart remains unconvinced and takes longer to come around. For me it was about deciding to live my life according to the Bible as many of my friends did and seemed to have a meaningful peace and happiness, however my heart knew that it would involve being more disciplined, less selfish and having to give some things up – it eventually came around but it was a slow process.
