Milton acknowledges that time is an irreversible force that spares nothing. He questions why life is so fleeting and why humans must endure the constant awareness of their mortality. He yearns for a way to escape the relentless grasp of time and preserve the precious moments of existence.
The poem also explores the themes of mutability, change, and the futility of human efforts to control or resist the passage of time. Milton muses on the inevitable decay and destruction that befall all earthly creations. He suggests that the only way to transcend time's tyranny is through faith in divine providence and the hope for eternal life in the afterlife.
"How Soon Hath Time" ends on a contemplative note, as the poet accepts the inevitability of death and expresses his trust in God's ultimate wisdom and design. Despite the fleeting nature of human existence, Milton finds solace in the belief that the soul will persist beyond the boundaries of time and experience everlasting joy in God's presence.
