Isn't the government, in some significant sense, already doing God's work? If the government encourages what is good and helps repress evil/destruction, isn't that God's work? If my taxes are going toward good things in that sense, I'm thrilled about it. So long as it includes the interests of the tax payer, it's good in terms of government helping folks. In the same context, the church can do things differently, or at least with different interests. The church can give liberally, without self-interest, in the context of a government that does its God-given job. Our power is our unity in love.
I hear you. I mean, what can one person really do? You never know, we might get it together one day.
