This World is Not My Home

I think reading this in context is best. Paul basically tells us that if you are a Christian, then you should gladly put away certain behaviors in exchange for more Christ-like characteristics with-in yourself. Once you have "become a new creature in Christ", all the bad behaviors you once had should be done away with, as you are no longer that person anymore.

It also calls us to do away with prejudices, such as racism, judging according to financial standings, or thinking you are better than anyone else because of your social placement (employer/employee relationship, etc.) Those systems do not exist in the Kingdom of God.


Colossians
Chapter 3
1 If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God.

2 Set your affection on things above, not on things on the earth.

3 For ye are dead, and your life is hid with Christ in God.

4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.

5 Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:

6 For which things' sake the wrath of God cometh on the children of disobedience:

7 In the which ye also walked some time, when ye lived in them.

8 But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.

9 Lie not one to another, seeing that ye have put off the old man with his deeds;

10 And have put on the new man, which is renewed in knowledge after the image of him that created him:

11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.

12 Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering;

13 Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.

14 And above all these things put on charity, which is the bond of perfectness.

15 And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.

16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.

17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
