It is also the process of creation in Genesis 1. Father, Son, Spirit - thought, word, deed. That is why we say that a word puts a person in action. In any mundane activity, this is the order. Thoughts are preparatory.
Deeds are the products.
Speaking the decisive word transmutes the thought into deed. The word is at the heart of the process. So a person in action is really his word in action. Now we are the sons of God operating in the Spirit kingdom, though outwardly flesh members of a three-dimensional world. Not one iota of difference.
