We are to preach good news to the poor, to set at liberty those that are oppressed and to proclaim the acceptable year of the Lord. Knowing our place in the army of God gives us the wisdom and knowledge to be able to come out of Babylon, denounce the oppression and minister to those that God would have us minister. Those in the movement may not all be saints but the good news is that Jesus will justify them anyway, they are being saved for the Kingdom on earth. They will be God's people bearing witness during the tribulation, especially during the latter days. Wisdom is crying in the streets, it doesn't always have to look pretty.
American society is especially oppressive to the poor.
There is the distorted image that poverty is the cause of crime and it is reflected on the criminal justice system. This bias against the poor is reflected at every stage from arrest to conviction. Many of the victims are poor. Our jail and prisons are full of those unable to pay for a good lawyer or simply can't pay the fine. A poor person is more likely to be arrested for petty crimes than a rich person.
