The sound of summer
I don't know what does it for you but when I hear Swifts screeching above me, I know summer has arrived.
They're just brilliant: sweeping, banking, cutting through the sky, and seemingly having such a great time of it. I know that's something of an anthropomorphism but how else to explain the sight and sound of them? I can't help (sentimental chump that I may be) but see a kind of joy in them, and find my hopes for the complete joy promised by Jesus educated.
How wonderful of God to create creatures that soar above us, to make so many things above us that cause us to look up, wonder, and dream.
