Therefore do not worry, saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?’ For it is the Gentiles who strive for all these things; and indeed your heavenly Father knows that you need all these things. But strive first for the kingdom of God and his righteousness, and all these things will be given to you as well. Matthew 6:31-33
The Bible repeatedly warns us not to obsess over wealth, for the love of money leads to much dissatisfaction, grief, and evil.
5 Keep your lives free from the love of money, and be content with what you have;
for He has said, “I will never leave you or forsake you.” Hebrews 13:5
In Mark chapter 10, Jesus commanded the rich young ruler to sell everything he had, give it to the poor, and follow Him. And in Mark chapter 12, He singled out the poor widow who gave all she had as a model of heroic generosity. But these are the extremes, not the biblical rule.
