Athanasius of Alexandria, on Isa 1:2

“Hear, O ye heavens, and give ear, O earth, for the Lord hath spoken. I have brought up children, and exalted them: but they have despised me.”

“The one who is [begotten] from another by nature is a true child, just as Isaac was to Abraham, and Joseph was to Jacob, and as the radiance is to the sun. But those who are called children only from virtue and grace are called so not by nature but because of what they have received by grace. They still are not of the same nature as the one who gave them [the gift]. They are the ones who received the Spirit by participation, about whom it is said, "I produced and exalted children, but they rebelled against me." Of course, they were never really children by nature, and because of this and the fact that they reverted [to their former ways], the Spirit was taken away and they were disinherited. But when they again repent, God will receive them again and give them light. He will again call them children who at the beginning had been given grace.”
