Question to Christians?

Old testament wasn't written for the gentiles, it was written for the Jew. You also must look at the context in which it was. We live in the spirit of the old law in accordance with the new covenant The old covenant was meant to bring us to Christ to paint a picture of what Christ will do and why we need a Savior. It is not null and void, but it has been revised by the death burial and resurrection of Christ.
