Financial Virtues Series: Prudence (Wisdom) with Dr. Greg Forster
Faith & Finance with Rob West
“The one who gets wisdom loves life; the one who cherishes understanding will soon prosper.” — Proverbs 19:8
Wisdom doesn’t just shape what we believe. It shapes how we live—including how we handle money.
That’s why prudence has long been considered one of the cardinal virtues. It’s not a word we use every day, but it speaks directly to the way Christians make decisions, set priorities, manage resources, and seek to honor God with what He has entrusted to us.
In this new series on the financial virtues, Dr. Greg Forster, Affiliate Professor of Biblical and Systematic Theology at Trinity Evangelical Divinity School (TEDS) and Executive Director of the Christian Investing Council (CIC), joined the show today to discuss prudence and why faithful stewardship requires more than financial knowledge.

What Is Virtue?
Before we can understand prudence, we first need to understand virtue.
Dr. Forster defines virtue as becoming a Christlike person. It is not merely doing the right thing outwardly. It is developing Christlike qualities in our character so that we obey God from the heart.
Jesus often exposed the danger of outward obedience without inward transformation. He spoke of “whitewashed tombs” that looked clean on the outside but were full of death within. He also warned against cleaning the outside of the cup while leaving the inside filthy.
Those images remind us that God cares not only about what we do, but also how and why we do it. That is especially important when it comes to money.
Faithful stewardship is not a checklist. It is not simply giving a certain amount, following a set of financial rules, or making decisions that appear responsible on the surface. Stewardship is relational. It is part of our worship. It is one way we bring our whole selves before the Lord and say, “This belongs to You. How can I use it for Your purposes?”
The Cardinal Virtues and the Christian Life
The cardinal virtues—prudence, temperance, fortitude, and justice—come from a long tradition in Christian moral reflection. The word “cardinal” comes from the Latin word for the hinge of a door. These virtues are “hinge” virtues because they help guide and shape the others.
Christian ethics has often distinguished between theological virtues, which are known through God’s revelation in Scripture, and moral virtues, which are more broadly recognized because God has made His moral order known through creation and conscience.
That matters for two reasons.
First, it reminds us that all people are accountable to God. Even those who have never read the Bible still live in God’s world and bear His image.
Second, it gives us a foundation for shared life with neighbors who may not share our faith. There are moral truths people can recognize because God has woven them into the world He made.
Among those moral virtues, prudence has often been seen as especially important because it helps us discern how to put wisdom into practice.
What Is Prudence?
Prudence is often described as wisdom in action.
It is not simply about having good goals. It is knowing the right means to pursue those goals faithfully.
As Dr. Forster explained, we often say, “The ends don’t justify the means.” In other words, having a good goal does not give us permission to pursue it in careless, wasteful, or sinful ways. Prudence helps us ask, "What is the right course of action?" What is the wise path forward? How do we pursue good ends in a way that honors God?
That makes prudence deeply practical.
It moves us from abstract desire to concrete obedience. It is one thing to say, “I want to be more Christlike,” or “I want to be a faithful steward.” It is another thing to ask, “What decision should I make today? What habit needs to change? What plan will help me move toward faithfulness?”
Prudence is where the rubber meets the road.
Prudence in Scripture
The book of Proverbs is one of the clearest places we see prudence in Scripture. Proverbs repeatedly teaches that God cares not only about the goals we pursue, but also the path we take to reach them.
Wisdom is practical. It shows up in our words, our work, our planning, our relationships, and our use of money.
Jesus also points us toward prudence when He tells His disciples to be “wise as serpents and innocent as doves.” Innocence matters, but so does wisdom. Christ calls His people to pursue holiness with careful thought, discernment, and faithfulness.
Paul gives a similar charge in Ephesians 5:15–16: “Look carefully then how you walk, not as unwise but as wise, making the best use of the time.” That is a call to prudence. We are to pay attention to how we live, how we spend our days, and how we steward the opportunities God gives.
Prudence draws us closer to Christ by moving us beyond surface-level obedience. It asks us to bring our motives, priorities, decisions, and plans under His lordship.
Why Financial Rules Are Not Enough
Financial rules can be helpful. Budgets, savings goals, debt repayment plans, and investment strategies all have their place. But rules alone cannot produce faithful stewardship.
God is not merely after outward compliance. He desires fellowship with His people.
Dr. Forster illustrated this by pointing to human relationships. We would never say in our families or friendships that motives do not matter as long as someone does the right thing. A parent does not merely want a child to obey externally while remaining distant, resentful, or unchanged inwardly.
The same is true in our relationship with God.
If we are only asking, “What is the minimum I have to do with my money to feel like I’ve done my duty?” we are missing the deeper invitation. God calls us to see all that we have as His and to ask how we can use it for His purposes.
That kind of stewardship is not mechanical. It is worshipful.
Wisdom in Action
Prudence is wisdom in action. It is the virtue that helps us choose the right means to faithfully pursue God’s ends.
As Christians, we do not manage money merely to become more efficient, comfortable, or secure. We manage what God has entrusted to us because He is Lord over all of life.
That means our financial decisions are never just financial. They are spiritual. They reveal what we value, what we trust, and what kind of people we are becoming.
And by God’s grace, prudence helps us become stewards who do not merely know what is right, but who increasingly learn to walk in wisdom.
On Today’s Program, Rob Answers Listener Questions:
Last year, I sold gold nuggets on eBay for about $7,000 and received a 1099. When I filed my taxes, I paid tax on the full amount, even though eBay charged more than $1,000 in seller fees. Once I receive my refund, can my tax preparer file an amended return so those fees are deducted?
Several years ago, my son and daughter-in-law borrowed about $6,500 from us to build a tiny house. They’re now selling it at a loss and using the proceeds to repay us, with about a $3,000 net loss overall. Are there any sales tax or income tax consequences for them or for us, or is this simply a personal loss?
I recently tried to pay in cash, but the business said they couldn’t make change and would have to keep the difference, which pushed me to use a card. Then I had a conversation with someone interested in Bitcoin. As Christians, how should we think about digital money, Bitcoin, and the move away from cash? What’s the wisest way to approach it?
