Oh brother, let me clarify what I say.
The answer to your question is that I wouldn't be a politician. It is a role that I would refuse.
If you read what I said again, you would see that I said that we SHOULD feed the poor among us. A politician should indeed feed the poor.
But as disciples of Christ, our first priority is not social justice, we know that God will set things right in the end, and we follow his command; follow me! Even if the poor are there. We are not there to try and figure out the worlds social justice problems, we are there to shine the light of Christ.
Yes, that includes taking care of and loving our neighbor, and the poor and widows we encounter. We do that, but we don't let that be our focus. Christ says 'if you do not hate your mother, father, brother, etc, you can have no part with me'. What he's saying is that unless your love for them is like hatred compared to your love for HIM, you can have no part with him. How much more then is that true of our neighbor, and all those around us, whether wealthy or in need?
Paul did not go around raising orphanages, he went around raising churches (Christ through him). As a result, yes, everything is shared, people are fed and helped. That is good. But that is not the ultimate aim. The aim is Christ; we shouldn't aim for anything else. To be conformed to his image, to walk in his power, and to spread his Gospel.
Blessings :)
