He said nothing of a book that would combine the
old covenant scriptures with the account of His
life on earth and letters that were written to people who
lived under the law, that people who have never
lived under the law would have to try to discern and apply to their
lives until He returned, or they died.
Under the
old covenant there was no holy spirit in man to help them obey but for believers today there is no excuse cause we have the empowering of the holy spirit to help us today to be obedient Revelation 22:14 (Bless are they that do his commandments that they may have right to the tree of
life and may enter in through the gates into the city obedience is the key.
