The New Testament mentions two covenants. There is the old covenant of Moses, and then the new covenant of Jesus Christ. The reason God gave us a new covenant is that the behavior of many people under the old covenant was not in keeping with God’s standards of righteousness, holiness, and obedience.
The Apostle Paul endeavored to make clear to the Jews that they cannot be saved by obeying the Law of Moses but by putting their faith in the Lord Jesus Christ. Paul's words have been corrupted to mean we are saved by our belief system apart from any effort to live righteously or serve the Lord. It is a spiritually fatal interpretation.
