When Americans hear the name George Washington, we think of courage, perseverance, and leadership. When we hear the name Benedict Arnold, we immediately think of disloyalty and betrayal. The same Revolutionary War that revealed the exemplary character of Washington also exposed the heart of Arnold.
The Christian life is no different.
Times of suffering and hardship have a way of revealing what lies beneath the surface. Trials expose whether our deepest affection belongs to Christ or to this present world.
Satan informed God that Job only worships Him because of all the blessings he enjoys (wealth, health, respect and fame). Take those gifts away and Job will abandon You (God) and curse your holy Name. Few saints are taken through a job-like time of testing.
As noted earlier, trials expose whether our deepest affection belongs to Christ or to this present world. Few biblical examples illustrate this truth more vividly than Luke and Demas.
Their names appear together in Paul's letters. Both traveled with the apostle. Both witnessed the advance of the gospel. Both appeared to be trusted ministry partners.
Yet by the end of Paul's life, one remained faithfully at his side while the other abandoned him.
The difference was not opportunity.
The difference was affection.
A person's true spiritual condition is ultimately revealed by what he loves most (note also John 21).
Luke loved Christ. Demas loved this present world.
Their choices and the path they ultimately choose to travel upon revealed their hearts.
I. Luke: The Quiet Faithfulness That God Delights to Honor
One of the most remarkable things about Luke is how little he says about himself.
Although he wrote both the Gospel of Luke and Acts—nearly one-fourth of the New Testament—he never draws attention to himself. Instead, he consistently points readers to Christ, to the work of the Holy Spirit, and to other saints.
Paul simply calls him "the beloved physician." Those two words tell us much about Luke's ministry. He cared for Paul's physical needs while also serving as a trusted companion through imprisonment, persecution, and countless hardships.
True Christian greatness is often quiet. Though Christian conference speakers typically pastor large churches in affluent areas the most faithful shepherds are generally unheralded servants.
Luke never preached at Pentecost.
He was not the "main guy." He never became the public face of the missionary movement.
Instead, he faithfully served where God placed him.
Every church needs faithful Lukes.
Some preach and teach. Some lead.
Some encourage. Some assist.
Some quietly and tenderly care for hurting saints.
Most will never have their names written in history books, but every act of faithful service is remembered by God (1 Cor. 4:2). Luke was a faithful and loyal ministry partner to Paul because Christ was his first-love. He was an invaluable part of Paul's core team.
II. Demas: When Love for the World Wins
If Luke's life encourages us, Demas should sober us.
When Paul wrote Philemon, Demas was called a "fellow worker." No one reading that letter would have predicted how his story would end.
Years later, Paul writes with unmistakable grief:
"Demas, having loved this present world, has deserted me..."
Notice that Paul does not merely say Demas left.
He tells us why he left.
His heart had found another treasure.
The Greek wording emphasizes an ongoing affection. Demas didn't simply make one poor decision in a difficult moment. This was not just a rough patch. His love for the present age eventually showed that he did not truly love the Lord Jesus Christ.
Eventually, what fills the heart directs the feet.
III. The Question Every Christian Must Ask
The story is not merely about Luke and Demas.
It is about us.
Every believer is moving in one of those two directions.
Are we becoming more steadfast?
Or more distracted?
More devoted?
Or more divided?
Jesus taught that where our treasure is, there our heart will be also.
What we truly love always reveals who we truly are.
Christ, the (only) Perfect Servant of God.
Thankfully, this passage is not merely a warning.
It is also an invitation.
Unlike Demas, Jesus never abandoned His mission.
He remained faithful all the way to the cross.
When His (believing) disciples fled, Christ stood firm.
When the cost became unimaginably high, the Son of God obeyed His Father perfectly.
Because Jesus remained faithful, sinners who trust Him can be forgiven, transformed, and preserved.
The same grace that sustained Luke is available to every believer today.
May God make us a church filled with men and women who finish well.
May our greatest love never be this present world.
May it always be Jesus Christ.
