The mixing of Law with Grace is in our opinion the most damaging theology for believers. In Grace there is no Law. To add it is like adding a drop of poison to a cup of water. 

Law isn’t just the Old Testament Mosaic Law – it is anything we do to try to please God or look good on the outside. It’s doing to be rather than being which results in doing. How do we unwittingly try to make the two work together? By adding our own works to what Christ has already done.
