If, on the other hand, we wish to call Him ‘Word’ because He is in everything, we shall not be mistaken: did not the Word create all that is?… He is called ‘Life’… because He gives life to everything. Indeed, ‘in Him we live and move and have our being’ (Acts 17.28)… It is from Him that we all receive the breath of life and the Holy Spirit Whom our soul contains to the limit of its openness. - "Fourth Theological Oration, 20-21"

For of course even this, if nothing else, of itself was a help to them— that the heaven is in every place, that it stands in all time. (f) See how (he declares) His Providence, and His upholding power (συγκράτησιν); the existence of all things from Him, (from Him) their working (τὸ ἐνεργεἵν), (from Him their preservation) that they perish not. And he does not say, Through Him, but, what was nearer than this, In him.— That poet said nothing equal to this, For we are His offspring. He, however, spoke it of Jupit...
This is said by Aratus the poet. Observe how he draws his arguments from things done by themselves, and from sayings of their own. Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like gold, or silver, or stone, graven by art.
