“The Bible’s purpose is not so much to show you how to live a good life. The Bible’s  purpose is to show you how God’s grace breaks into your life against your will  and saves you from the sin and brokenness that otherwise you would never
be able to overcome…
Religion says ‘if you obey, then you will be accepted’. But the Gospel claims that  'if you are absolutely accepted, and sure you’re accepted, only then will you ever  begin to obey’. Those are two utterly different things. Every page of the Bible  shows the difference.”
~ Tim Keller, The Centrality of the Gospel
