There are 3 main flows of life. The life of the human body is in the blood (Leviticus 17:11). If a body’s blood stops flowing, it dies.
The life of the world system is money. If a worldly organization’s money stops flowing, it dies.
The life of the church is in the Spirit. If the Spirit stops flowing, then the church dies spiritually. However, a dead church can easily morph into what appears to be life by keeping the money flowing, turning into a worldly organization.
Emaciated or dead churches that are kept flowing via money use 3 main cornerstones of teaching to accomplish keeping the organization alive.
They teach on hell to keep the people in fear.
They teach heavily about sin to keep the people in guilt and shame.
These two keep the people coming to church, but not out of hunger for life, but out of fear, guilt, and shame.
Then they teach tithing to separate the people from their money, and have it flow into the organization.
