In the first century B.C., Roman historian Sallust observed, “Prosperity tries the souls, even of the wise.” Most of us would probably choose financial prosperity over adversity. Yet both seasons bring their own spiritual challenges. When things are going well financially, it can be tempting to take credit for our success. Pride, greed, and self-reliance can quietly take root. Financial hardship brings different temptations—self-pity, bitterness, envy, or fear. Scripture offers a better way. Christians are called to live faithfully and with integrity regardless of their circumstances. And according to the Bible, the key to doing that in both prosperity and adversity is wisdom.
