The Apostle Paul in his writings speaks of a man named Demas three times. We know very little about Demas, but through the writings of Paul we see a decline in his Christian walk. His name means "governor of the people". Perhaps, Demas had many leadership qualities that were admired and warranted the attention of the Apostle Paul.
The Apostle in Colossians says:
Colossians 4:14 Luke, the beloved physician, and Demas, greet you.
Colossians was written between 60 - 64 AD. Demas is obviously in the presence of Paul as a friend and mentee. I can imagine that when Paul was writing the letter that Demas yelled out, please tell the church at Colosse that I send greetings. It was a close relationship.
In the letter written to the Paul's close friend, Philemon, the Apostle penned:
Philemon 1:23 - 24 There salute thee Epaphrus, my fellow prisoner in Christ Jesus; Marcus, Aritarchus, Demas, Lucas, my fellowlabourers.
Paul calls Demas a fellow-laborer. According to Thayer's, this is defined as, "A companion in work." They stood shoulder to shoulder in preaching the gospel of Jesus Christ to a lost world.
The scripture that Demas is most known for was written in a letter to Timothy between 66 - 69 AD:
II Timothy 4:10 For Demas hath forsaken me, having loved this present world, and is departed unto Thessalonica...
Demas had been with or around the Apostle Paul for at least a few years. In reading these scriptures, it would be easy to warn others of the decline of Demas. We have no idea what happened after II Timothy. Perhaps, he was a prodigal that found his way back. But these scriptures should be convicting to us because it teaches we need to stay near to our pastors and build boundaries around ourselves to keep the darkness of the world from invading our life.
Demas was a promising preacher working with the Apostle Paul. His name defines him as a leader, but he walked away from the things of God because he loved the things of the world more.
A guy named Demas lost his way so I challenge you to look in the mirror, check your priorities and stay near your pastor. I am.
