Standing on the foundation of Scripture is a body of truth that you must believe. If you reject that body of truth, you are not a Christian.
First, can we agree that a true Christian is someone who embraces those truths by faith?

Third, what can we do (as individual Christians) to see that evangelicalism is characterized once again by proclaiming all those truths faithfully? In other words, what can we do to restore the evangel to evangelicalism?
