Danny Aiken co-wrote a blog entry on how the modern day church needs to be more diverse in its methodology.
Our convention must confront the brutal facts:
In Matthew 28:18-20, Jesus commands us to make disciples of all nations. This includes our own nation-the United States of America-and yet the truth is that we are failing to meet the challenge. While the population of our nation increases, the population of our churches has not kept pace. While the United States becomes increasingly diverse, the Southern Baptist Convention remains a mostly middle-class, mostly white, network of mostly-declining churches. This is a painful truth, and to ignore this fact is the worst form of denial.
It is not as if the churches of the SBC have not tried to reach their own towns and cities. Many of them have worked hard to reach their cities and many of them have more or less succeeded. But the truth of the matter is that we are losing the battle. Our nation is becoming increasingly post-Christian and we are not stemming the tide. Perhaps one of the reasons that we are losing the battle is that we are “aiming at” a culture that no longer exists. The SBC built its programs and its personality, if you will, in the 1950s. But we find ourselves in a socio-cultural context that varies significantly from that of 50 years ago. Many of our churches no longer have the luxury of communicating the gospel within a city that has basically one culture. Instead, they find themselves communicating across numerous cultural and sub-cultural divides.
