For the persons who say that the first testament has no value? (been abolished)?

There is no confusion if you are part of Jehovah's worldwide education work. There is a difference between the old law covenant being done away with and saying the entire Hebrew scriptures being irrelevant. Quite the opposite the Hebrew scriptures is of great value. It harmonizes and gives support to the Greek scriptures and helps with insight into Gods plan and his nature. It makes up the majority of the Bible and it essential for Christian study.
