Origen, on 2Tim 2:19

“But the sure foundation of God standeth firm, having this seal: the Lord knoweth who are his; and let every one depart from iniquity who nameth the name of the Lord.”

“Those who have been made one with and united with something know that with which they have been made one and have been united. Yet before such unity and participation, even if they objectively grasp something of the explanations given about a thing, they still do not know it.… For, in our view, the Lord has known those who are his because he has been made one with them and has given them a share of his own divinity and has taken them up, as the language of the Gospel says, into his own hand, since those who have believed in the Savior are in the Father's hand. For this reason also, unless they fall from his hand—thereby removing themselves from the hand of God, they will not be snatched away, for no one snatches anyone from the Father's hand.”
