This Book consists of two booklets. Booklet One reveals what the Lord Jesus Christ did and taught about Sabbaths. Booklet Two reveals the truth concerning circumcision. Why is it important to understand the teaching concerning Sabbaths? Jesus persisted in doing works on Sabbaths which were opposed by the religious authorities because they interpreted the works of Jesus Christ as breaking the fourth commandment of the Law. If Jesus had broken the fourth commandment then He could not have fulfilled the Law. That is why it is important to have full knowledge of what constitute obedience to the law concerning Sabbaths. Jesus Christ actually fulfilled the whole Law and that included the law about Sabbaths. There is no doubt in the gospel of salvation that all New Testament believers must fulfil the law as taught by Jesus Christ in Luke 16:16-17; Matthew 19:16-21 and Luke 10:25-28. The teachings in many so-called Christian sects is that the fourth commandment is of no relevance to New Testament believers. Yet there are also so-called Christian sects which believe that New Testament believers must fully obey the law concerning Sabbaths as prescribed according to the Old Testament practices. Booklet Two reveals the truth concerning circumcision. One of the main reasons Paul was persecuted by the Jews was his teaching that the practice of circumcision is of no relevance to New Testament believers. In fact Paul warned uncircumcised believers that if they believe it was necessary for them to be circumcised to be saved then they have believed the gospel in vain. The Jews were opposed to this teaching of Paul was because like Sabbath, circumcision of flesh is an everlasting covenant Jehovah made with Abraham and his descendants, Israel. How can an everlasting covenant be discarded in the New Testament by the same God who made that covenant with Abraham and Israel? Even Jewish believers from Jerusalem preached to gentile believers that they must be circumcised in order for them to be children of Abraham and hence to receive the promise of everlasting life. Paul was equally persistent in his opposition to the insistence by the Jews and Jewish believers that the gentile believers must be circumcised in order to be saved. Paul revealed to the gentiles and Jews the irrelevance of circumcision of flesh in the gospel of salvation. Believers insisting to be circumcised as part of the requirement to receive everlasting life, their belief in the gospel was in vain. Paul was the only apostle given the revelation by Jesus Christ concerning the irrelevance of circumcision of flesh because he was called to be an apostle to the gentiles. While Peter, Barnabas and others were unsure of their position as believers into Christ on this topic of circumcision to those uncircumcised believer. This booklet reveals the true meaning of circumcision and how it shoud be understood and practised in New Testament days. Like other important topics such as worship, love, works, law, Sabbath, etc. the Old Testament understanding of such important issues was inadequate and incomplete and could not provide the full knowledge and understanding in relation to the gospel of salvation. Believers who continue to follow the understanding and hence the practices of such issues and in particular circumcision according to Old Testament knowledge will not be able to complete their salvation journey to receive everlasting life. All New Testament believers must also be circumcised according to the true understanding of its meaning in order for them to become overcomers to receive everlasting life.
