I think I understand the argument in Galatians 3:19a about the purpose of the law. But then in the second half of the verse, Paul begins, “The law was given through angels and entrusted to a mediator. A mediator, however, implies more than one party; but God is one.” (NIV)
What argument is Paul making in bringing up a mediator/intermediary and then countering that God is one? Or is this just a side note he’s adding?
