Jesus’ own words here are a timeless reminder to live in the present moment. It doesn’t mean we cannot plan for the future, but we shouldn’t get so wrapped up about future matters that we become anxious and worrisome.
I liked the hourglass as a symbol of time, and the flower is a nice touch because—prior to this verse—Christ had just spoken about flowers:
And which of you by being anxious can add one cubit to his span of life? And why are you anxious about clothing? Consider the lilies of the field, how they grow; they neither toil nor spin; yet I tell you, even Solomon in all his glory was not arrayed like one of these. But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, O men of little faith?—Matthew 6:27-30 (RSVCE)
