In When The Good News Becomes Bad, Dr. R. Scott Clark gives an informative overview of the historical and biblical context for properly understanding the Gospel, and especially its distinction from the Law. Explaining the importance of the topic, Dr. Clark writes:
The word “Gospel” is so familiar and frequently used that it is possible to lose sight of its genuine meaning, “good news.” This question is vital as we face a series of movements within our churches which seek to redefine the meaning of the Gospel. In each case we are being offered “another Gospel” (Gal 1:6). The Good News of Christ faces a threat on the order of that faced by the Galatian Christians.
