Epistle to the Colossians
The second part of the letter, chapters 3 and 4, tells the Christians how to live based on what they know about Jesus.  They are told to think about things that are above, to kill the bad desires of their old nature, and to put on the new (Christian) person. Many special duties of the Christian life are also taught.  These show that we are true Christians. The letter ends with prayer, instruction, and greetings.
