This poem, like so many of Frost's poems, takes as its subject the beauty of nature. The title, "A Prayer in Spring," points towards the way in which this poem operates as a simple evocation of the beauty of God's creation in spring and it expresses sincere thanks for the wonders that surround the speaker. This is marked by the repetition of "Oh, give us pleasure..." as the speaker asks to be satisfied with the natural wonders that surround him, rather than focusing on the "uncertain harvest" of the future. Delight is taken in the immediate pleasures and beauty of the blossom on the fruit trees, which are described as being:

Like nothing else by day, like ghosts by night.

Note the way the beauty of the blossom is emphasised by the description of them as being like nothing else by day, and then comparing them to ghosts by night, which emphasise the whiteness of the petals and their other-worldly beauty. Likewise, the "darting bird" is described as:

The meteor that thrusts in with needle bill,
And off a blossom in mid-air stands still.

Such images capture the beauty of springtime, and this is all described in the last stanza as "love" which is "reserved for God above." Thus the poem acts as a poem of praise of the beauty of God's creation and encourages us to enjoy the present rather than focusing on the worries of the future.
