4 There is therefore one God, who by the Word and Wisdom created and arranged all things; but this is the Creator (Demiurge) who has granted this world to the human race, and who, as regards His greatness, is indeed unknown to all who have been made by Him (for no man has searched out His height, either among the ancients who have gone to their rest, or any of those who are now alive); but as regards His love, He is always known through Him by whose means He ordained all things.
Now this is His Word, our Lord Jesus Christ, who in the last times was made a man among men, that He might join the end to the beginning, that is, man to God. Wherefore the prophets, receiving the prophetic gift from the same Word, announced His advent according to the flesh, by which the blending and communion of God and man took place according to the good pleasure of the Father, the Word of God foretelling from the beginning that God should be seen by men, and hold converse with them upon earth, should confer with them, and should be present with His own creation, saving it, and becoming capable of being perceived by it, and freeing us from the hands of all that hate us, that is, from every spirit of wickedness; and causing us to serve Him in holiness and righteousness all our days, in order that man, having embraced the Spirit of God, might pass into the glory of the Father.
