Do you know David Stern? He is a jew and a translator of the jewish new testament. In the introduction of the new testament he writes some things which are really confusing. Stern is of the opinion that the new testament has first of all been recorded in hebrew and not in greek. He also thinks that the new testaments which we have have been mistranslated because the translators do not know the jewish background of certain words. For example Stern believes that Jesus did not come to put away with the law, to fulfill it, but he believes that Jesus came to fill the law up. So according to Stern trying to live according to the law is not negative at all. This is really confusing. Does he really believe that a messianic jew or maybe even a christian should try to keep all those rules in the old testament? How in the world is this supposed to be possible? Doesn't Paul make clear that it is not possible and that trying to hold the law doesn't make sense because if you only fail once you fail completely? But then again Paul also said other things which confuse me, such as these here: Act 21:19 And when he had saluted them, he declared particularly what things God had wrought among the Gentiles by his ministry. Act 21:20 And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law: Act 21:21 And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs. Act 21:22 What is it therefore? the multitude must needs come together: for they will hear that thou art come. Act 21:23 Do therefore this that we say to thee: We have four men which have a vow on them; Act 21:24 Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law. Act 21:25 As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication. Act 21:26 Then Paul took the men, and the next day purifying himself with them entered into the temple, to signify the accomplishment of the days of purification, until that an offering should be offered for every one of them. Why would Paul make an offering? Wouldn't he step out of the grace by doing so? And does verse 24 mean that a messianic jew has to keep the law while a normal christian doesn't have to?
