So now that you are a Christian, how then ought you to live- To the Thessalonians Paul wrote, -... dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus.- The Apostle, from chapter 12, verse 1, has been working out the meaning of -obey the gospel of our Lord Jesus-. You, enjoying the empathy of the Lord Jesus,must model your living after Him and thus also empathize with others.
