Demas (means “popular”)
-appears three times in the Holy Bible (Colossians 4:14, Philemon 1:24, 2 Timothy 4:10) In Philemon, Demas is mentioned as a fellow labourer with the apostle Paul. He also sends greeting along with Paul in Colossians. In Timothy he forsakes the apostle Paul having loved this present world and departs to Thessalonica. Demas was a fellow labourer in the ministry with Paul. So it is likely that Demas was a preacher and a great Christian. What happened? His heart turned back to Egypt having loved this present world.
1 John 3:15-17 Love not the world
Demas is a good example of a biblical truth: It doesn’t matter how you start, it matters how you finish. There are many examples of Christians starting out good, and then falling away for one of the reasons we talked about. Paul said, I have fought a good fight, I have finished my course, I have kept the faith. He was faithful unto death. At salvation God has given you a great start. He has given you of his Spirit, and his Word, and there are still some good Bible believing churches around and the rest is up to you whether you will love the Lord Jesus Christ and obey him in all things. The most general thing I can say to you that sums up what God expects of you from the day of your salvation to the day of the salvation of your body is CONTINUE in THE FAITH (John 8:31, John 15:9, Acts 13:43, Acts 14:22, 1 Timothy 4:16, 2 Timothy 3:14, Colossians 1:21-23).
