A great quote from Frederick Buechner:
"Repentance is coming to your senses. It’s not something you do as much as something that happens. True repentance spends less time looking at the past and saying ‘I’m sorry,’ than to the future and saying, ‘Wow!’"
This is an outstanding quote and if we took it seriously would redefine how we talk about grace and the fact that the Christian life is not about giving up stuff as much as it is embracing and expressing our godly destiny.
