Proof No. 1 New and better covenant

In light of the superiority of the new and better covenant of the grace of GOD (Heb. 8:6-7), over the old covenant called the  Law of GOD (Deut 4:13; 2 Chron 33:8), New Testament believers' allegiance must inevitably be to Christ and his new testament directives, instead of to old testament ones, which, although were appropriate for old testament times, are, in many instances, unsuited for the new testament believer in Jesus Christ.
