Who is John Wesley? And What Can We Learn from Him?
John Wesley (June 28, 1703 – March 2, 1791) was a Church of England cleric and Christian theologian who taught – and lived out – some financial principles which continue to challenge us today.

Gain all you can.
Perhaps because he grew up in poverty, witnessing his father (an Anglican priest in one of England’s lowest-paying parishes) being marched off to debtor’s prison, John accepted a more lucrative position: teacher at Oxford University. Rather than believing, as some did, that money was inherently evil, Wesley thought of all the good one could do with money...more money meant more good. John Wesley knew how to earn money, and he did so quite well.

Save all you can.
Saving, to Wesley, meant not spending. Being a single man most of his life, he stored very little of his earnings for the types of savings we deem non-negotiables today, such as emergency funds or retirement nest eggs. He urged his followers to purchase only the absolute basic necessities of life, rightly noting that purchases of expensive food, fancy clothing and elegant furniture was wasteful. But he also pointed out that when people spend money on things they do not really need, they begin to want more things they do not need. Because people who would never waste money on themselves might be more indulgent with their children. Wesley especially warned against buying too much for children. Based on the principle that gratifying a desire needlessly only tends to increase it, he asked these well-intentioned parents: “Why should you be at further expense to increase their temptations and snares and to pierce them through with more sorrows?”

Give all you can.
An event which occurred while Wesley was at Oxford greatly impacted his views on giving. Evidently, after purchasing some pictures for his room, he noticed one cold winter day that one of the chambermaids had nothing to protect her except a thin linen gown. When he reached into his pocket to give her some money to buy a coat, he found he had too little left. Immediately, the thought struck him that the Lord was not pleased with the way he had spent his money.

Wesley became known for his saying, “What should rise is not the Christian’s standard of living, but his standard of giving.”
He continued this practice his entire life. Even when his income reached 1,400 pounds, he lived on 30 pounds and gave the rest away. Wesley was afraid of laying up treasures on earth, so the money went out in charity as quickly as it came in. He reports that he never had more than 100 pounds at any one time.

How about today?
You may be thinking, “I certainly admire John Wesley for his principles and his commitment to living out those principles. But surely we can’t be expected to live up to those same guidelines in today’s world.”
These decisions are between you and your spouse and God. But we can be challenged by these principles. Maybe you don’t forgo your emergency savings or your retirement savings, but perhaps seriously consider ways to maintain your standard of living in order to increase your standard of giving.
