Jesus Christ kept the Ten Commandments (Luke 4:8; John 15:10), and taught others to do likewise (Matthew 19:17-19). He elaborated on keeping them in Matthew 5:21-22, 27-28. Jesus emphatically says, "If you want to enter into [eternal] life, keep the commandments." Could anything be clearer? John writes, "He who says, 'I know Him,' and does not keep His commandments, is a liar, and the truth is not in him" (I John 2:4). Paul instructs Timothy, "Let everyone who names the name of Christ [calls himself a Christian] depart from iniquity" (II Timothy 2:19).
