From Christ Died for the Sins of Christians Too:

I used to tell my students at an evangelical Christian college that they had never heard real preaching, with the exception of a few sound evangelistic appeals. Their weekly diet in the congregation was often a moral exhortation to be like Jesus, or Paul, or Daniel, or some other super saint in the Bible. They were constantly peppered with the question, “What are you doing for Jesus?” The preaching was not, as it should have been, a proclamation of God’s grace to them because of the finished and atoning death of Christ-God’s grace for them as Christians. That emphasis is desperately needed. But the only way we can recover this message is by ceasing to read the Scriptures as a recipe book for Christian living, and instead find within the Scriptures Christ who died for us and who is the answer to our unchristian living. We must have that kind of renewal (a renewal, which not surprisingly, was important to the reformers, as well), and it can only come if we realize that the gospel is for Christians, too.
