Colossians 4

1 Masters, give unto your servants that which is just and equal; knowing that ye also have a Master in heaven.

Don't treat those who work for you badly. You must be good to them knowing that if it wasn't for God, you wouldn't be blessed with them in the first place. Remember that ill gotten gains in any circumstance will bring destruction upon you.

2 Continue in prayer, and watch in the same with thanksgiving;

3 Withal praying also for us, that God would open unto us a door of utterance, to speak the mystery of Christ, for which I am also in bonds:

Pray our Father opens your ears and eyes to His Word, that you may teach and show others Christ. Being joined together in Truth, in knowledge of His Word. Today's Christians know very little of The Bible and it's because they won't give time to The Word and also because few "pastors" will feed you more than a few verses on that one day each week you go to church. We need to study and pray for understanding daily.

4 That I may make it manifest, as I ought to speak.

"Manifest" φανερόω phaneróō, fan-er-o'-o; from G5318; to render apparent (literally or figuratively):—appear, manifestly declare, (make) manifest (forth), shew (self), to make known by teaching, to make manifest or visible or known what has been hidden or unknown, to manifest, whether by words, or deeds, or in any other way. Pray to be able to teach, that they will understand HIS WORD.

5 Walk in wisdom toward them that are without, redeeming the time. Let your speech be always with grace, seasoned with salt, that ye may know how ye ought to answer every man.

It's not about winning friends or growing your church. Plant The Truth, never watered down or sugar coated, but given in love for others that they also may come to the knowledge of The Truth.  Matthew 5:13 Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.  Be that bold, salt that stings the wounds of evil. Speak up! Fight the good fight! We have enough sugar coated Christians in the world today.  2 Timothy 3:7 Ever learning, and never able to come to the knowledge of the truth.  Nothing is being taught in most Christian churches today. So many go into their church, get a few verses and come out empty. Milk by itself will never help you grow. Sooner or later you need meat.

6 Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.

Use common sense. If you have someone truly wanting to know something in The Word, show them favor with love and knowledge. Do your very best to help them come to The Truth.

7 All my state shall Tychicus declare unto you, who is a beloved brother, and a faithful minister and fellowservant in the Lord:

Tychicus = "fateful", a Christian friend and companion of the apostle Paul.

8 Whom I have sent unto you for the same purpose, that he might know your estate, and comfort your hearts;

Tychicus is going to teach the Colossians with grace, seasoned with salt, that they will grow in strength with faith.

9 With Onesimus, a faithful and beloved brother, who is one of you. They shall make known unto you all things which are done here.

Onesimus = "profitable or useful".

10 Aristarchus my fellowprisoner saluteth you, and Marcus, sister's son to Barnabas, (touching whom ye received commandments: if he come unto you, receive him;)

Aristarchus = "best ruler", a Christian of Thessalonica who accompanied Paul on his third missionary journey.

11 And Jesus, which is called Justus, who are of the circumcision. These only are my fellowworkers unto the kingdom of God, which have been a comfort unto me.

Jesus was a very common name. "Justus" Ἰοῦστος Ioûstos, ee-ooce'-tos; of Latin origin ("just"); Justus, the name of three Christian: Justus = "just", a surname of Joseph, called Barsabas. Acts 1:23, of Titus, a Christian at Corinth, with whom Paul lodged. Acts 18:7 and a surname of Jesus, a friend of Paul. 

12 Epaphras, who is one of you, a servant of Christ, saluteth you, always labouring fervently for you in prayers, that ye may stand perfect and complete in all the will of God.

Epaphras = "lovely"

13 For I bear him record, that he hath a great zeal for you, and them that are in Laodicea, and them in Hierapolis.

14 Luke, the beloved physician, and Demas, greet you.

Luke or Lucus = "light-giving" and a Christian companion of Paul's preaching the gospel on his many journeys; he was a physician and author of the books of Luke and Acts in the New Testament.

15 Salute the brethren which are in Laodicea, and Nymphas, and the church which is in his house.

16 And when this epistle is read among you, cause that it be read also in the church of the Laodiceans; and that ye likewise read the epistle from Laodicea.

That all would come to know The Way to salvation through Christ.

17 And say to Archippus, Take heed to the ministry which thou hast received in the Lord, that thou fulfil it.

Archippus = "master of the horse"

18 The salutation by the hand of me Paul. Remember my bonds. Grace be with you. Amen.
