There are only 11 small pages plus a discussion guide to this minizine, so it's pretty easy to read. It covers the case for both social involvement and evangelism, then combines them in part 2, "How they relate".
There the following points are made: that these are distinct activities, that proclamation is central, and that though distinct, they are inseparable.
The authors use the example of our godliness to show that how we "do" things (being godly) does not produce new Christians, but shows our new life in Christ to the world. In the same way, they suggest, social involvement (using our resources and gifts to help those around us) must also be part of our Christian faith, even though it cannot on its own bring people to Christ.
Making these statements as clearly as it does means the minizine is likely to be very useful to anyone, or any church, considering where and how they can engage in helping the poor and weak around them in the world.
