Romans 5 Offending God

Romans 5 is on my schedule for Sunday. Paul once again deals with personal responsibility - accountability for our actions. I noticed that Thayer said an offense is a "deviation from truth and uprightness". It seems to be identified with the outcome of "amartia". It is a purposeful activity and not accidental in nature [paraptwma]. BB Taylor wrote that it consists of a "wrecked relationship with God." I fear we have become so callosed by sin that we do not even care if we offend a fellow believer [whom we can see], let alone God [whom we cannot see] .
