Jesus said, "Recognize what is in your sight, and that which is hidden from you will become plain to you. For there is nothing hidden which will not become manifest."
Gospel of Thomas 4
I roll my eyes so many times when I hear people marketing "secrets" to prosperity, love, or power--aims that can have results in the spiritual world or material world. What's always "secret" really isn't--it's just a reframing of what's been known for centuries repackaged in an expensive box.
The message is always there but remains hidden from us because we've put material things over our spiritual eyes. We find it difficult to perceive beyond the senses.
Watching the leaves change day by day reminds me of this passage from the Gospel of Thomas, particularly about what is hidden. All things are in a state of change, but we might not perceive those changes unless we step back and take snapshots of the winter, spring, summer and autumn. We might believe nothing is happening in the winter--it is "hidden," so we can't see the leaf in full bloom just yet.
The buds in the spring contain the revelation, too, yet still we don't perceive the potential of the leaf. Yet in the summer, when the leaf is green and vibrant, we also know that in its flourishing is also its gradual surrender.
In the autumn, the leaf experiences life and death at the same time--green and yellow--yet it eventually surrenders, lets go, knowing that it is following the will of God.
And still, we can obsess over a single leaf, or we can step back and observe the tree, the forest, or nature itself as an expression of God.
