Uncountable numbers of people have endeavoured to live their lives according to Scriptures.
That may or may not be true. Can you site an example of any religious organization [prior to the WTS] promoting that practice? I have not found this teaching anywhere in history prior to the 19th century American bible boom. Please cite any examples that I may have missed.
I would cite the family of Jesus who made the sacrifices, observed the festivals etc of the Jewish scriptures. I can’t imagine Joseph being unscrupulous in his dealings with others . In the early Christian world a lot met their death in the arena rather than violate their beliefs
Living according to righteousness is NOT strictly living according to the scriptures.
The scriptures in Jesus's time [and today too] were read aloud in worship at the Synagogue through today in Church[s]. It was never a complete guide to faithful life. It included worship,a record of history of a race of people, a guide on cleansing and diet. Laws , etc
Today millions of Christian people believe they are living the right way , the trouble is the application of Bible principles. e.g. A JW would not vote or stand for office because he must be “ no part of the world “ . However , a Mormon may tell you that it is Christian duty to do so , for the good of the community.
History teached all the way back to the apostles that the right way to live as a Christian is to do ALL that Jesus instructed us to do. Jesus NEVER said look to the scriptures as a guide for living, he DID say to do all that he told us to.
