Charlotte Brontë's poem begins with three images involving rain: the morning rain that precedes a pleasant day, the dark rain-clouds that soon disperse and the showers that make roses bloom. In the first case, the rain makes the brightness of the day that follows all the sweeter; in the second, the threat of rain turns out to be empty, for the clouds are transient; and in the third, the rain actually brings a benefit.
The poem proceeds to deal with more serious threats to Hope: Death and Sorrow. Against these, Brontë sets the resilience of Hope:
Yet Hope again elastic springs,
Unconquered, though she fell;
Still buoyant are her golden wings,
Still strong to bear us well.
This quality of Hope is invoked to exhort the reader to similar resilience. Just as Hope will rebound from the onslaughts of Death and Sorrow, so we can bear any trial if we will be courageous. The parallel is emphasized both by the personification of Hope as a woman and by the similar language used in the description of her conduct and the reactions demanded from us. As Hope is "strong" and "unconquered," so we must be "fearless" and "victorious" in the conquest of despair. In doing so, we not only avoid losing hope but become like the personified Hope herself.
