I believe prosperity doctrines are false, IF:
1. they don't include the soul - 3 John 1:2 "Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth."
2. they include the love of money - 1 Timothy 6:10 "For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows."
3. they believe richer is better - Matthew 19:24 "And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God."
