How are Christians not under the Old Testiment?
The OT Law is not a law to us...It is a teacher...We will not go to hell for violating the law...Because there is no one who can live their life without violating the law at some point...
And that is why Jesus died on the Cross...He put all of our law violations, past, present and future on Himself...He payed it all...Once, for all time...We (Christians) are debt free...
Should we try to live by the Ten Commandments...Of course...The Commandments teach us what sin is...And the Holy Spirit within the body of Christians guides us to avoid that sin...Unfortunately, we don't always listen to him...
