Agency is a term of art suggesting that a person is authorized to act on behalf of another. Where there is no agency, there is no authority, and where there is no authority, there is deception. A church that refuses to tithe in accordance with biblical principles, or that encourages others to tithe in a manner that is not in accordance with biblical principles, is not an agent of the Lord God Almighty, the Lord God Father in heaven El Elohim, or the Lord God Jesus Of Nazareth, cannot be trusted, and should not be your home church, or the church to which you tithe and pay offerings.
Find a church that tithes in accordance with biblical principles by asking the Holy Spirit that is in you for the location of the nearest church. If there are none, join with others and start one, and the Lord God Almighty will be with you.
