Church commitments the cause of poverty?
This may apply to all the churches on your island but it does not include Jehovah’s Witnesses!
Nothing is given under duress or required to be part of their organization.
Everything is voluntary and not compulsory! You can willingly donate/contribute whatever is within your means or want to out of a loving heart!
You should examine their organization and teachings more closely to see what it means to serve God freely!
