Paul is saying that Christ was made poor because God deigned to be
born as man, humbling the power of his might so that he might obtain for men
the riches of divinity and thus share in the divine nature, as Peter says. He
was made man in order to take man into the Godhead. As it is written: I have said, you are gods In
this way he is exhorting them to become like poor people, so that their poverty
might be beneficial to us. Christ was made poor, not for his sake but for ours,
but we are made poor for our own benefit. (Ambrosiaster, Commentaries on Romans and 1-2 Corinthians
