If you refuse to live by the new law (the "LAW OF LIBERTY", James 1:25 and 2:12) then you will be considered to be LAWLESS.
The Old Testament is basically the HEBREW BIBLE.
MOST of what Jesus says in both old and new testaments is said to the JEWS (MOST)....we can easily recognize what is meant for us by the Spirit).
We should also be aware that Jesus spoke to the Jews in figures of speech (poetic license of sorts).
John 16:25 said this to you IN FIGURES, the hour is coming when I shall no longer speak to you in figures
Jesus abolished the 10 commandment law (the law of sin).
Eph 2:15 by abolishing in his flesh the law of commandments and ordinances
2Ti 1:10 who abolished death and brought life
If that is not clear enough(the law of sin caused DEATH).
Heb 2:14 that through death he might destroy him who has the power of death, that is, the devil,
James 1:25 and...
JAMES 2:12 are to be judged under the law of liberty.
....the OLD law (10 commandment law) has been abolished/destroyed. The new "law" is not an OPTION, it is A LAW/mandate.
Not living/abiding by the NEW LAW WILL MAKE YOU A "MAN OF LAWLESSNESS".
