The primal sin of humanity is idolatry, worshipping and trusting that which is not God and so losing the glory of God. This stands in stark contrast to what happened when Abraham believed God and trusted that He could do what He had promised (Rom 1:18–25; 3:23; 4:18–21). That is part of the larger logic of Romans 1–4 as a whole. The reversal of the fall of humanity and the renewal of the whole cosmos is the theme of God’s overall plan of salvation. Within this scope, the saving plan for humanity is one vital part; we are justified in order to be justice-bringers, saved to be the agents of salvation for the world. God’s plan always was to rescue the world through Israel: This has been accomplished through Jesus, Israel’s representative Messiah.
