Pastor and TV preacher, John Avanzini, says that no matter what the current economic circumstances indicate, no matter what the state of the country, you can have more than enough if you operate according to God's investment plan.
"We are down to the final days - the time when you either do what the world says or you do what God says." ~ John Avanzini, Always Abounding, p. 108
This book has biblical principles that pertain to God's economics based on the Scriptures in the Bible. I found this book very sound and emphasized the power of sowing and reaping.
I liked the chapter on how it is God who promotes us and not man. (See Psalms 75:6)
