Tithing

 Nowhere in The New Testament does it say the apostles ever instructed the believers to pay tithes. Paul teaches that giving is completely voluntary (2 Corinthians 9:6-7). 
                                                                                                                           Tithing in the Law of Moses was not about giving. It was about tithing which was required by the law. To not tithe would be breaking the law.
                                                                                                                                    New Testament believers are no longer under the Law of Moses (Romans 7:6; Galatians 5:1). 

                                                                                                                                  Tithing is a personal decision.
