How can ' Something'.....?

It can't. in the existence of all things seen and unseen, everything that is made was created by a spoken word, the Word of Almighty God. The box as you say clearly holds nothing but the box itself has material value and had it's start from the word that brought it forth into existence. Though some would think that the box has always been, which is not true. The box represents matter and matter consists of everything seen and like life in itself was spoken forth and God created the first man Adam. God never changes, His creative word will produce life in peoples broken body, broken relationships and marriages,. He is able to speak forth a word to change us from the inside out. He is able to turn any bad situation around for our good but we also have to change our way of thinking as well as the words we say for we also have creative abilities in our words for life and death are in the power of the tongue, given us from above...
