Acts 19:13 & Matt 7:21-23: False Believers?
How does Acts 19:13 connect with Matthew 7:21-23 about false believers?

Text Under the Microscope

Acts 19:13: “Then some of the itinerant Jewish exorcists tried to invoke the name of the Lord Jesus over those with evil spirits. ‘I adjure you by the Jesus whom Paul proclaims,’ they said.”

Matthew 7:21-23: “Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only those who do the will of My Father in heaven. Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name drive out demons, and perform many miracles?’ Then I will tell them plainly, ‘I never knew you; depart from Me, you workers of lawlessness.’”


Common Threads: Words Without Relationship

• Both texts feature people who invoke Jesus’ name verbally yet lack saving relationship with Him.

• Each group expects spiritual authority or reward because of what they say or do in His name.

• Both passages end with failure and exposure—demonic defeat in Acts, final judgment in Matthew.

• The core issue is not the name “Jesus” on their lips but the absence of genuine faith and obedience in their hearts (cf. James 2:19, 1 John 2:4-5).


Superficial Use of Jesus’ Name

Acts 19 shows professional exorcists treating Jesus’ name like a magical incantation—“the Jesus whom Paul proclaims.” They recognize power but remain outsiders.

Matthew 7 depicts professing believers flaunting ministries performed “in Your name,” yet Jesus disowns them.

• Both illustrate 2 Timothy 3:5: “having a form of godliness but denying its power.”


True Authority Flows From Personal Union

• In Acts, the demonic spirit replies, “Jesus I know, and Paul I know about, but who are you?” (v. 15). Demons recognize authentic spiritual authority that springs from union with Christ (Luke 10:17-20).

• In Matthew, Jesus’ verdict hinges on relationship: “I never knew you.” The decisive factor is being known by Him (John 10:14, 2 Corinthians 5:17).

• Authority is delegated to those indwelt by the Spirit, not to mere imitators (Acts 1:8; Galatians 4:6-7).


Warnings for Today

• Religious activity—even spectacular ministry—can mask an unregenerate heart.

• Borrowed language, borrowed formulas, or borrowed testimonies cannot substitute for personal repentance and faith (Acts 2:38).

• Public success is not proof of private surrender (1 Samuel 16:7).

• Final judgment will expose every counterfeit (1 Corinthians 4:5).


Markers of Authentic Faith

• Obedience to the Father’s will (Matthew 7:21; John 14:15).

• Intimate knowledge of Christ (Philippians 3:8-10).

• Indwelling Holy Spirit bearing witness (Romans 8:16).

• Fruits of righteousness evidencing new birth (Matthew 7:17-20; Galatians 5:22-23).

• Perseverance in truth, not just momentary enthusiasm (John 8:31).


Living It Out

• Examine whether you know His name or merely use it (2 Corinthians 13:5).

• Cultivate daily fellowship with Christ through Scripture and obedience (John 15:4-5).

• Depend on the Spirit for genuine authority rather than techniques or traditions (Zechariah 4:6).

• Let every act of service flow from love for the One who first loved us (1 John 4:19; Colossians 3:17).
