Nothing wrong with seed time and harvest. Give and it shall be given. Sow sparingly, reap sparingly, sow abundantly and reap abundantly. If you are doing things out of the love of money, that is wrong. You should expect more from God so that you can give more. I will defer on my personal views of Copeland because I am not his judge, nor do i know his giving or teaching that well.
To me the bigger problem is that Christians do not discern on where or how to give their money. If you are unsure where to give I encourage any believer to take a trip overseas to a poor nation of your choice. It will change at least part of your giving.
I will comment on the the word of faith teacher Kenneth Hagin. Hagin's bible school is Rhema, which sometimes is called out for some students who went on to be prosperity teaching pastors. To be fair though, Hagin addressed having a balanced view of prosperity in his book "The Midas Touch."
Here is a synopsis I found on it.
"The mythical King Midas wanted everything he touched to turn to gold. But when he got what he wanted, he soon discover he didn't want what he got! Kenneth E. Hagin often dealt with the issue of prosperity for believers during nearly 70 years of international ministry. In
The Midas Touch, he explains that following unscriptural teachings can lead the Christian into either a "poverty mentality" or an unhealthy focus on money and things. Both of these are dangerous ditches along the road of life. Rev. Hagin emphasizes a balanced, biblical approach - steering a course down the middle of the road."
I asked google ai about Hagin and his issues with an unscriptural biblical prosperity.
- "Sowing a Seed" to "Reap a Specific Item": Hagin explicitly denounced the practice of giving money (sowing a seed) with the expectation of receiving a specific, tangible return, such as "sowing a Ford and reaping a Mercedes". This "heavenly vending machine" approach was a gimmick Hagin felt corrupted the nature of giving.
- The "Hundredfold Return": Hagin rejected the popular teaching that believers should expect a specific "hundredfold return" on their giving, calculating that if this were universally true, all Christians would be "quadrillionaires".
- Debt Cancellation Gimmicks: Hagin was highly critical of ministers who promised "supernatural debt cancellation" to those who gave in certain offerings, calling it a scheme to raise money for the preacher.
- Lifestyle and Excess: Hagin warned against making material wealth the sole sign of spirituality, noting that "drug traffickers and crime bosses would be spiritual giants" if that were the case
- Focus on Motive: Hagin emphasized that the motive for giving should not be personal gain, as focusing on what one will receive "corrupts the very attitude of our giving nature".
"In summary, Hagin's teachings laid the groundwork for the modern prosperity gospel, but he later attempted to distance himself from what he considered manipulative and unscriptural practices." Though Hagin is often villfied for the prosperity gospel, to me, he shows as straight of path as one can get as far as I can tell and I have read many of his books.
