John Gill emphasizes the transitory nature of human life and glory, comparing it to grass and flowers that wither and fade. He explains that all flesh is frail and mortal, highlighting that both the righteous and the wicked face death, yet the word of God remains eternal. Gill contrasts the fleeting nature of worldly achievements and honors with the everlasting truth and riches found in the Gospel. He notes that while earthly glory is temporary, the spiritual wealth and righteousness offered through Christ endure forever. This sermon serves as a reminder of the importance of valuing eternal truths over temporary worldly pursuits.
