4:6 Abba. “Abba” is the Aramaic word for “father” (perhaps more like “papa”). The cry of the Spirit in our hearts is thus, “Abba, Father,” using both an intimate name and a respectful name for one’s father. It was actually the expression used by Jesus as He prayed in the Garden of Gethsemane (Mark 14:36). See also Romans 8:15.
