“But Who Are You?”
We are introduced to an amazing experience in Acts 19:15–16 (NLT), wherein the Scripture says, “But the evil spirit replied, ‘I know Jesus, and I know Paul, but who are you?’ Then the man with the evil spirit leaped on them, attacked them with such violence that they fled from the house, naked and badly injured.”
There is a question in this passage that ought to make every one of us stop and examine our hearts: “But who are you?” The seven sons of Sceva had witnessed the power of Jesus' name. They saw Paul preach, heal, and minister in the authority of Christ. So they tried to imitate what they had seen. They attempted to cast out a demon, saying: “I command you in the name of Jesus, whom Paul preaches, to come out!” But there was one major problem. They knew about Jesus—but they didn't know Jesus. The evil spirit responded: “I know Jesus, and I know Paul, but who are you?”
That question exposes the danger of operating in spiritual authority without a genuine relationship with Jesus Christ. They had the right words. They used the right name. They had seen the right ministry. But they didn't have the right relationship. And that is a sobering warning for us.
Church attendance doesn't make us followers of Jesus. Knowing Scripture doesn't automatically mean we know the Author. Having a ministry title doesn't mean we have spiritual authority. Being around godly people doesn't make us godly. Knowing Christian language isn't the same as knowing Christ. We can learn how to say “Praise the Lord,” while our hearts are far from Him.
We can sing the songs. We can preach the sermons. We can teach the Bible. We can lead ministries. We can even impress people spiritually—and still fail to cultivate a genuine relationship with Jesus.
Jesus said in John 10:27: “My sheep listen to my voice; I know them, and they follow me.” The Christian life isn't primarily about performing for God.
It is about knowing God. The seven sons of Sceva wanted the power associated with Jesus without surrendering themselves to Jesus. They wanted the authority without the relationship. They wanted the results without the obedience. And their encounter ended in humiliation and defeat. But Acts 19 also gives us the other side of the story. When people witnessed what happened, they became deeply convicted. Verse 17 says: “The story of what happened spread quickly all through Ephesus, to Jews and Greeks alike. A solemn fear descended on the city, and the name of the Lord Jesus was greatly honored.” Acts 19:17 (NLT). The name of Jesus was greatly honored. That's what our lives should accomplish.
Not that people would be impressed with us, but that they would see Jesus. Not that people would remember our names, but that they would remember His. Not that people would say, “Look how powerful that person is,” but: “Look what Jesus has done!” So today, ask yourself: “Who am I?” Am I simply familiar with Jesus? Or do I actually know Him? Do I know His Word? Do I know His voice? Do I trust Him? Do I obey Him? Do I love Him? Am I following Him when nobody is watching?
The world doesn't need more people who merely talk about Jesus. It needs people who know Jesus. People whose lives demonstrate His grace. People whose character reflects His holiness. People whose actions reveal His love. People who aren't using Jesus for their own purposes but are completely surrendered to His purposes. Because ultimately, the question isn't whether we know Jesus' name. The question is: Does Jesus know us? May our answer be more than religious vocabulary. May our lives declare: “I belong to Jesus.”
Prayer: Lord Jesus, I don't want to know about You merely. I want to know You truly. Forgive me for the times I have focused more on religious activity than on relationship with You. Forgive me if I have ever tried to use Your name for my own purposes instead of surrendering my life to Your purposes. Search my heart and reveal anything that is not pleasing to You. Give me a deeper hunger for Your Word, a stronger desire for Your presence, and a greater willingness to obey You.
Let my life demonstrate that I belong to You. May I never seek recognition for myself when all the glory belongs to You. When people encounter me, let them see something of Jesus in the way I live, love, serve, forgive, and respond. Lord, may my life never cause people to ask, “But who are you?” May it cause them to see and honor who You are. Let the name of Jesus be greatly honored through my life, in the mighty name of Jesus, Amen.
