Acts 20:28-38 CSB
Be on guard for yourselves and for all the flock of which the Holy Spirit has appointed you as overseers, to shepherd the church of God, which he purchased with his own blood. [29] I know that after my departure savage wolves will come in among you, not sparing the flock. [30] Men will rise up even from your own number and distort the truth to lure the disciples into following them. [31] Therefore be on the alert, remembering that night and day for three years I never stopped warning each one of you with tears. [32] "And now I commit you to God and to the word of his grace, which is able to build you up and to give you an inheritance among all who are sanctified. [33] I have not coveted anyone's silver or gold or clothing. [34] You yourselves know that I worked with my own hands to support myself and those who are with me. [35] In every way I've shown you that it is necessary to help the weak by laboring like this and to remember the words of the Lord Jesus, because he said, 'It is more blessed to give than to receive.'" [36] After he said this, he knelt down and prayed with all of them. [37] There were many tears shed by everyone. They embraced Paul and kissed him, [38] grieving most of all over his statement that they would never see his face again. And they accompanied him to the ship.
Matthew 24:4-5 CSB
Jesus replied to them, "Watch out that no one deceives you. [5] For many will come in my name, saying, 'I am the Messiah,' and they will deceive many.
Brotherly Embrace
How can we recognize a false prophet—those smooth-talking individuals who quietly slip into a community of believers, claiming to have unique spiritual authority, but are actually blind guides leading people entirely astray?
During Paul’s era, the single greatest threat to the young church came from the legalists. These were teachers who insisted that before a person could truly be saved by Christ, they first had to conform to the entire ceremonial law of Moses, including strict dietary codes and circumcision. Paul repeatedly and fiercely went to battle against this heavy distortion. He continuously pointed people back to the beautiful simplicity of the cross: we are saved strictly by grace through faith in what Jesus accomplished for us on Calvary. It is never a matter of our own human works or behavior; it is entirely the Father who works out our salvation.
So, how do we protect ourselves today? How can we discern if a teacher, author, or online personality is a false guide, subtly inflating their own importance while quietly steering people away from the truth?
We can look to a wonderful, reliable tool given to us in the New Testament: the biblical litmus test. In a laboratory setting, a litmus test is a simple, effective indicator used to establish the true chemical nature of a solution. By dipping a small strip of treated paper into a liquid, the immediate color change tells the researcher exactly whether they are dealing with a dangerous acid or a safe base.
The Apostle John gives us two distinct, practical tests in his first letter to check the spiritual chemistry of anyone claiming to speak for God.
The first test focuses on core theology: 1 John 2:22 tells us that the true deceptive spirit is anyone who denies that Jesus is the Christ. Those who try to reshape the identity of the Son or diminish His full divinity are exposed by the truth.
The second test focuses on personal fruit: 1 John 3:4-10 explains that you can accurately discern a person’s true spiritual condition by looking closely at the way they actually live their everyday life. The one who consistently practices righteousness is of God; whereas the individual who remains comfortably trapped in a lifestyle of deliberate, unrepentant sin has neither seen the Lord nor truly known Him.
Now, does this mean a genuine Christian will never make mistakes or stumble into sin? Of course not. If that were the case, Jesus would have had no reason to die a brutal death for us on the cross, and John would not have explicitly instructed believers to continuously confess their sins to a faithful and just Father. There is a vast, monumental difference between a believer who occasionally falls into sin but is deeply broken, contrite, and repentant over it, and a false guide whose consistent lifestyle is quietly filled with worldly desires, greed, and hidden manipulation. In time, a false teacher is almost always uncovered when the hidden veneer finally slips, a public scandal hits, and their true colors are laid bare before the community.
As Paul reminds us on that emotional beachside, guarding the purity of the Gospel from those who would pervert the truth is our shared responsibility. This ongoing battle to keep the message pure must always be done out of deep love for Christ and His people. It is certainly not a task for the timid, and at times, the spiritual opposition can feel incredibly fierce.
Knowing his time was short, Paul beautifully reminds his friends that he never once coveted their silver, gold, or fine clothing. He didn’t view ministry as a career path to personal wealth or comfort. Instead, he chose to labor exhaustively with his own two hands as a leatherworker to support not only his own daily physical needs, but the needs of the missionary team traveling alongside him.
By living this way, Paul beautifully modeled an incredible, unwritten saying of Jesus that is preserved nowhere else in the four Gospels except right here in Luke’s record of Paul’s speech: “It is more blessed to give than to receive.” Paul understood that the true heart of a shepherd is to be a suffering servant, pouring himself out completely for the benefit of those around him.
When the final goodbyes were spoken and the tearful embraces were finished, the leaders knelt together in the sand to pray. Surrounded by a deep, brotherly love, Paul was tenderly accompanied to the waiting ship that would carry him toward Jerusalem—and ultimately, into the waiting courts of Rome.
Reflection Questions
- Paul explicitly warns that false teachers can rise up “even from your own number.” Why is it harder to spot spiritual deception when it comes from someone inside our own circles, and how can we guard against it without becoming cynical or untrusting of our leaders?
- The author uses the example of a litmus test from 1 John to check both a teacher’s core beliefs about Jesus and their daily lifestyle. When you look at the voices you listen to most (in books, podcasts, or church), how do they measure up against this dual test of healthy doctrine and Christlike fruit?
- Paul treasured an oral saying of Jesus—“It is more blessed to give than to receive”—and lived it out by working with his hands to support others. How can we practically apply this “giving lifestyle” in our current neighborhoods, families, and other circles this week?
Prayer
Father,
You are the Great Shepherd of the sheep, and You purchased Your church at the highest possible cost—the precious blood of Your own Son. We thank You for the faithful leaders, past and present, who have watched over our souls with humility, tears, and sacrificial love. Give us discerning hearts and sharp spiritual eyes to immediately recognize anyone who would try to distort Your truth or lead us away from the simplicity of the cross. Protect our local churches and families from divisive and deceitful influences. Help us to live out the beautiful truth that it is truly more blessed to give than to receive, pouring out our lives to serve the weak and encourage the weary. Hold us fast in Your grace, and keep our steps steady until we see You face to face. In the matchless Name of Jesus we pray.
Amen.
