Christianity has become nothing more than pious gush. This gush is characterized by such statements as, "I believe that the desire to tithe comes from a heart that is committed to Jesus Christ." This definition of tithing is emotional and fuzzy. It is subjective to the core. It is based upon feelings rather than logic and reason. It is a statement made by an antinomian (against law).
Tithing is judicially based. It is based upon an objective standard. "Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings." (Malachi 3:8). To not tithe is to steal from God. The eighth commandment says, "Thou shalt not steal." Those who do not tithe are stealing from God. Can a thief be a Christian?
I can hear the argument that this was Old Testament law for Israel, to which I would respond that God is immutable. His law has not changed. Besides all that, the Church has replaced the nation of Israel as God’s chosen people (Galatians 6:16 and Matthew 21:43).
Do not respond to this letter with emotion. Back up what you say with scripture and in context. Saying that tithing is a matter of the heart is not scripturally based. It makes tithing optional and becomes a tradition of man rather than what it is based in law.
