The Sermon on the Mount's section on money and anxiety (Matthew 6:19–34) is one of the most sustained pieces of economic theology in the New Testament. Jesus covers hoarding, divided loyalty, and the anxiety that accompanies financial insecurity. His argument is not "don't worry about money because it doesn't matter." His argument is: you are worrying about the wrong things because you are trusting the wrong source. The birds and the lilies are not given as examples of God's generosity in good times — they are given as evidence of a God who is already providing for things that cannot ask him for anything.
Philippians 4:11–13 is one of the most misquoted passages in the Bible. "I can do all things through Christ which strengtheneth me" (verse 13) is almost always quoted without verse 11: "I have learned, in whatsoever state I am, therewith to be content." The contentment was not native to Paul. He learned it — over years, through being "abased" and through "abounding," through plenty and through hunger. The strength Christ provides in verse 13 is specifically the strength to be content in poverty, not just the strength to achieve goals. The context the prosperity gospel drops is the poverty.
The Old Testament provides a persistent theology of daily provision. The manna in the wilderness was given one day at a time. You could not stockpile it — those who tried found it rotten by morning. The Israelites had to trust that tomorrow's supply would come tomorrow. Proverbs 30:8 asks for neither poverty nor riches — "feed me with food convenient for me" — and gives the reason: too much leads to forgetting God, too little leads to theft. The prayer is for sufficiency, not abundance. This is a minority position in a culture of maximization, but it is the prayer of a very wise man.
