It is interesting how many of us have been influenced by the liberalism of the 1920s. Even in conservative Reformed circles the hope for society is placed in government agencies, political parties, and social programs. (Of course, we need to acknowledge that government is a creation ordinance.)
The church used to be that institution that met the needs of the poor, advanced the betterment of society, and promoted all of the 'social' aspects of the Gospel of Christ. In our day, we have handed those reins over for unconverted men and women to do through social programs.
If the church is to take back her rightful place in society, then she is going to need to set up the programs to meet these needs, in advance of those in need coming to her. I am as guilty as the next guy in not reaching out to the needs of the fatherless, widow, and (illegal) alien within our gates. May we all pour our energies into the body of Christ so that she can do that which she is called to do.
It is upon this brotherhood of [the] twice born sinner , this brotherhood of the redeemed, that the Christian founds the hope of society. He finds no solid hope in the improvement of earthly conditions, or the molding of human institutions under the influence of the Golden Rule... A solid building cannot be constructed when all the materials are faulty; a blessed society cannot be formed out of men who are still under the curse of sin. Human institutions are really to be molded, not by the Christian principles accepted by the unsaved, but by Christian men; the true transformation of society will come by the influence of those who have themselves been redeemed. True Christianity differs from liberalism in the way in which the transformation of society is conceived. But according to Christian belief, as well as according to liberalism, there is really to be a transformation of society; it is not true that the Christian evangelist is interested in the salvation of individuals without being interested in the salvation of the race. And even before salvation of all society has been achieved, there is already a society of those who have been saved. That society is the Church. The Church is the highest Christian answer to the social needs of man. -J. Gresham Machen, Christianity and Liberalism.
