“Does tithing correctly mean 10% before or after taxes?”
Tithing should always be from what we receive from the Lord, which is everything.
In the Old Testament when the Israelites were given God's commandments and laws, they were told to return the first born of every animal and the firstfruits of every harvest (see Leviticus 27:30–31 and Deuteronomy 14:22.)
“I do not belong to a local church. Would God consider gifts to a TV ministry as tithing?”
“The tithe as it was instituted by God in the Old Testament was for the purpose of taking care of the Levites and their families since they did not receive an inheritance in Canaan as did the other tribes. The Levites were given the responsibility of leading the nation spiritually by teaching the people to obey God's law.
