Colossians 4:14

"Our dear friend Luke, the doctor, and Demas send greetings." NIV translation

Other members of the ministry team included Luke (the same Luke that wrote the book of Luke) and a man that worked alongside him by the name of Demas. Paul was not so sure about Demas and so we do not know much about him.

Colossians 4:15

"Give my greetings to the brothers at Laodicea, and to Nympha and the church in her house." NIV translation

Although we do not know much about her, Nympha evidently opened her home to worshipers in Laodicea.

This is the same church that Jesus called "lukewarm" in Revelation chapter three. 

Colossians 4:16

"After this letter has been read to you, see that it is also read in the church of the Laodiceans and that you in turn read the letter from Laodicea." NIV translation

Although this letter was written to a specific group of believers, it had meaning and instruction for others as well. God even uses it for us today and the lessons are just as relevant.
