In Romans 2 Paul has laid a trap for anyone who thinks that the list of sins in chapter 1 isn't about them–reality is we are ALL on the hook for our choices & sin against God. Paul is attempting to deepen our understanding & experience of God’s Gospel which is what unites all of us out of our sin and into Him! In 2:12-16 he continues to develop the essential truth that God is not lenient, but He is undeniably fair & unmistakably firm in His judgment of everyone.
