Recently I read a theory that the tithe is a Old Testament law that is not required. McConnilve says that it is not necessary for Christians to give ten percent of their earnings as specified in the Old Testament. According to his theory, it is completely up to the individual on the issue of giving money or not and how much money they should give.
I have heard opposite theories where Christians are required to give 10% at the least and the more they give the more they are blessed. And they relate to the story of J. C. Penny. when Penny opened his first story he started giving 10% to his church. And as he began making money he continued to give more and more money to his church, eventually he gave God 90% and he was living off 10% and as the story goes J.C. Penny was blessed and today, his stores are still profiting as a corporation.
Whether you think that the tithe law is is absolute or obsolete, I think we can agree:
The old covenant required 10 percent. The new covenant does not specify a percentage, and since we do not have a clear command from Scripture, we cannot press a command for a precise percentage. However, the new covenant admonishes people to give what they can, and tithing still provides an instructive comparison.
And God will bless you for completing your duty to give back what is his to Him.
