We ought first to know that there are no good works except those which God has commanded, even as there is no sin except that which God has forbidden.
Martin LutherBeing by his faith replaced afresh in paradise and created anew, he (the believer)does not need works for his justification, but that he may not be idle, but that he may exercise his own body and preserve it. His works are to be done freely, with the sole object of pleasing God.
Martin LutherWhenever the true message of the cross is abolished, the anger of hypocrites and heretics eases and all things seem to be at peace.
