Title: Being understood from what has been made
No written revelation is necessary to prove and validate that God is, for even in the absence of material and spiritual creation God is.
The whole of creation is an open book of unseen forces and divine governance singularly attributed to the Creator so eternally powerful he had spoken into being a mind-boggling universe and all that there is, and yet so simple its light, its message, is visible to the eyes of the flesh and of the spirit. That is why even a child would want to know who made the birds and the bees, and the flowers and the trees, and the moon up above, and the thing called love.
