The Continuing Church of God has a sermon: Tithing Answers from the Bible, which is at its ContinuingCOG channel.
Is tithing biblical? Should Christians tithe? Did early Christians tithe? If tithing is appropriate, does it include tithing on wages? How are tithes calculated? What is an increase? Does one tithe on the gross or net salary after taxes? What about offerings? Does the Bible teach multiple tithes? Is the ministry entitled to compensation? What are tithes and offerings used for? To whom should tithes/offerings be sent?
