In Matthew 8:16, Scripture tells us, “When evening came, many who were demon-possessed were brought to Him, and He drove out the spirits with a word and healed all the sick.”
There’s something breathtakingly powerful in that phrase—with a word. Not a battle. Not a ritual. Not a long, drawn-out deliverance session. Just a word.

But what kind of word can drive out evil spirits?

The original Greek word used here is logos, the same used in John 1:1: “In the beginning was the Word (Logos), and the Word was with God, and the Word was God.”
Logos speaks to the eternal, divine utterance—God’s truth spoken with absolute authority. So when Jesus cast out demons with a word, He wasn’t just speaking a word—He was the Word. His very presence embodied authority over all spiritual realms.


Why Deliverance Is More Common in the New Testament

One of the striking contrasts between the Old and New Testaments is how rare demonic activity seems in the Old and how prevalent it becomes in the New. In the Old Testament, there are scattered references—like Saul being tormented by an evil spirit (1 Samuel 16:14) or a lying spirit sent into the mouths of prophets (1 Kings 22:21–23)—but there’s little mention of demons being cast out.

Why? Because Jesus hadn’t yet come.

In the Old Testament, the Holy Spirit dwelled on specific individuals for specific purposes—prophets, kings, judges, and those anointed for God’s work. They were vessels of temporary empowerment, not permanent indwelling. The general population did not have authority over the demonic realm. But everything shifted with Jesus.

When Jesus came, He brought the kingdom of God near (Luke 10:9). The presence of the Word made flesh created a supernatural confrontation. Darkness could no longer stay hidden. Evil spirits that once operated in shadows now had to reveal themselves in the presence of divine authority. And when Jesus spoke, they had no choice but to flee.


From “On” to “In”: The Holy Spirit’s New Residence

This transition is crucial:
In the Old Testament, the Spirit came upon people.
In the New Testament, the Spirit comes to live within believers.

Ezekiel prophesied this shift: “I will put my Spirit within you” (Ezekiel 36:27). And Jesus confirmed it: “He lives with you and will be in you” (John 14:17).

After Jesus’ resurrection and the outpouring of the Holy Spirit at Pentecost, believers were filled with the same Spirit that raised Christ from the dead (Romans 8:11). This meant that every believer now carries the authority of Jesus—His Spirit, His Word, His dominion. We don’t fight for victory; we fight from victory.


Dominion and the “Sons of God”

In Deuteronomy 32:8-9 (ESV, Dead Sea Scrolls version), we read that God divided the nations according to the number of the “sons of God”—spiritual beings with dominion over geographic regions. These “sons” (often seen as angels or divine beings) ruled territories in a delegated way, while God reserved Israel as His portion.

These territorial dominions are why Daniel 10 references a “prince of Persia” resisting angelic messengers. There were spiritual authorities over kingdoms—sometimes corrupt, often in opposition to God’s will.

But Jesus changed everything.

When Jesus came, He didn’t just come to redeem individuals—He came to reclaim territory. He declared in Matthew 28:18, “All authority in heaven and on earth has been given to me.” That authority had previously been dispersed to spiritual rulers. But in Christ, dominion was centralized under one Name.

Through the cross and resurrection, Jesus disarmed principalities and powers (Colossians 2:15). He reclaimed the nations—not just spiritually, but geographically. Now, the earth is the Lord’s and the fullness thereof (Psalm 24:1), and His Church is the instrument through which His kingdom advances.


His Word Still Speaks

So when Matthew 8:16 says Jesus cast out demons “with a word,” we now understand the full weight of that moment. That “word” wasn’t just sound—it was the divine Logos confronting cosmic rulers, asserting heaven’s dominion, and opening a new era where:

  • The Holy Spirit no longer hovers or visits, but indwells and empowers.
  • Believers carry kingdom authority to drive out darkness.
  • Jesus’ name and His Word are sufficient to break every chain.

Today, if you feel oppressed, overwhelmed, or bound by spiritual forces, take heart: One word from Jesus is still enough.

You don’t need the right formula or the perfect prayer. You need His presence. And through His Spirit in you, you now walk with the same authority He exercised on earth.

So declare His Word. Speak His Name. Stand firm. The same power that drove out demons in Matthew 8:16 is living within you. I hope this speaks to you, and I pray you have a blessed day!
