I love, love, love this simple poem by Christina Rossetti.
I notice that although the wind is invisible, it stirs a “trembling” – a resonance – a quickening, as seen in the trembling leaves. The wind, “passing through,” creates an action that is observable, even as its substance remains unseen.
I notice that in the second stanza, it is the bowing of the trees that tells the poet that the “wind is passing by.” She cannot see the wind – but she can see the deferential worship of the trees.
What do the children notice as they watch the effects of God’s power passing through us? What can they understand from our resonance with His presence? To Whom do they see us bow in worship?
