In this video, Paul rebukes those who were turning to Judaism and receiving the mark of conversion, which is circumcision, to be justified. He makes the case that the Torah leads people to belief, but cannot on its own, justify anyone. Only through belief in Yeshua is one justified - but it’s unto obedience. He also compares circumcision of the flesh with the circumcision of the heart. This is a very impactful teaching!
