John Wesley reflects on the transient nature of human life, comparing it to a dream that vanishes upon awakening. He emphasizes the folly of the wicked who live as if their earthly existence is eternal, forgetting their mortality and the reality of eternity. Wesley urges listeners to recognize the fleeting nature of life and to prepare for the inevitable awakening into eternity, where the true essence of existence is revealed. He highlights the importance of faith in Christ as the connection between the temporal and the eternal, encouraging believers to live with a constant awareness of their spiritual state. Ultimately, Wesley calls for a life rooted in the love of God, which transcends the shadows of this world.
