Please advise.
I am saying that Christians who perform actions that are meritorious (feeding the hungry, comforting the afflicted, etc.) are doing something entirely different than Jews following the Law given at Sinai.
When Christians discuss faith v works, it is not about following the Law at all.
We all agree that the Law did not provide righteousness. That is what Paul is saying in the passage you misunderstand. It has nothing to do with the need for Christians to do good things in order to make their faith real and not merely an empty confession.
