This song is about making good choices, doing the right things for the right reasons and being responsible for the choices we make. Actions speak louder than words, we show who we truly are, what is important to us by the choices we make. How many times have you seen people say they love you then treat you badly? That's not love. This song is not about getting the most out of life, its about a life well and thoughtfully lived. You are right, Christians aren't perfect, they are forgiven. That is a gift of love from Jesus, and we are supposed repay him by sharing that love with others.
