In the United States, there is currently a debate about whether preachers should contextualize the Gospel. Those who oppose contextualization view those who favor it as people who compromise and undermine the true Biblical Gospel in the name of winning a hearing. Some of those who advocate for contextualization claim that those who don't contextualize (as they define it) are are going to fail to reach the current generation.
I've done a number of posts that deal with the issue of contextualization, realizing that some readers may misunderstand where I am coming from, and exactly what I am advocating. For those who are confused about contextualization or who suspect that I may be compromising the Gospel by advocating for contextualization, I want to recommend Dr. David Sills recent blog post on Reclaiming Contextualization. Sills discusses what is proper contextualization, why it is necessary, and how the term has been abused and redefined in recent debates.
