Thomas Brooks emphasizes the fleeting nature of earthly riches and honors, comparing them to shadows, ships, bubbles, birds, dreams, arrows, and runners that swiftly pass away. He warns against the futility of striving for wealth, as it is ultimately uncertain and lacks true substance. Brooks illustrates that worldly possessions are merely illusions, devoid of lasting value, and can vanish as quickly as they appear. He encourages listeners to recognize the vanity of placing trust in material wealth, which can be lost through various unforeseen circumstances. The sermon serves as a reminder to seek eternal treasures rather than temporary gains.
