Paul asks these rhetorical questions after being accused of giving Christians a license to sin in Romans 5:20…”The Law was added so that the trespass might increase. But where sin increased, grace increased all the more…” But here rather, Paul is explaining the unearned and unmerited free gift of God’s favor to all mankind called Common Grace…which is the doctrine of sovereign grace God bestows upon all of mankind regardless of their election. But as Christians, we have died to sin, so we can’t continue in it. Now this doesn’t mean we’ve somehow become sinless…by no means! It simply means that sin is no longer our master.
