You need to get into the NT and study Hebrews and the prophesies the Lord fulfilled including the institution of the New Covenant, you know the Covenant of Grace.
Christians have been freed from the Law, if they have been saved by grace through faith in Jesus Christ. Now, you have filled your posts with definitions and have missed the whole point of salvation by grace and what grace is according to God's word.
Your take on Christianity is so legalistic it falls far short of a true knowledge of what the Lord taught, let alone what the OT prophesies reveal concerning God's Messiah.
Are you a member of the Church of Christ?
I have asked you a number of questions, which you have steadfastly refused to answer, however I am going to ask you another one. Have you studied Galatians? Your legalisim is exposed as false teaching in view of both Galatians and Hebrews.
