Evidence of the Spirit: Understanding the Signs

When people talk about the Holy Spirit, you’ll hear a lot of different “signs” mentioned.
A sudden boldness.
A deeper hunger for God.
A transformed character.
Spiritual gifts.
And in Pentecostal churches (like ours), you’ll often hear one phrase in particular: the initial physical evidence of the baptism in the Holy Spirit.
So what does that mean?
And how do we talk about it in a way that’s biblical, Spirit-filled, and not confusing or divisive?
Let’s walk it out together: anchored in Scripture, aligned with the Assemblies of God (AG) 16 Fundamental Truths, and grounded in the real goal: knowing Jesus and being empowered to live and witness for Him.
Two Experiences, One Savior: Salvation and Spirit Baptism
Before we talk about “evidence,” it helps to get clear on the experience we’re talking about.
1) Salvation: New life in Christ
The greatest miracle is when a person turns to Jesus.
We believe:
The Bible is God’s inspired Word and our authority.
Jesus is God’s Son, born of a virgin, sinless, crucified, raised, and returning again.
Everyone has sinned and needs forgiveness.
We’re saved by grace through faith, not by earning it.
Water baptism is an outward sign of an inward work.
That’s the foundation.
If you’ve repented and put your faith in Jesus, you belong to Him.
2) Baptism in the Holy Spirit: Empowerment for witness
In Acts, we see believers who already followed Jesus receive a distinct experience of being baptized in the Holy Spirit.
Jesus described the purpose clearly:
“You will receive power when the Holy Spirit has come upon you, and you will be my witnesses…” (Acts 1:8)
This isn’t about getting a spiritual “badge.”
It’s about God empowering ordinary people to live boldly for Christ: often in hard places, confusing seasons, hostile environments, or quiet, unseen everyday life.
For shift workers, caregivers, people isolated by disability, believers in persecuted regions, or anyone feeling spiritually drained: this matters.
God doesn’t just call you.
He empowers you.
What Does “Initial Physical Evidence” Mean?
In Assemblies of God theology, we believe:
The initial physical evidence of the baptism in the Holy Spirit is speaking in tongues as the Spirit gives utterance.
That language comes from watching a consistent pattern in the book of Acts, especially:
Acts 2:1–4 (Pentecost)
Acts 10:44–46 (Cornelius’ household)
Acts 19:1–6 (Ephesus)
In each of these accounts, when people were baptized in the Holy Spirit, there was an outward, observable sign: and specifically, they spoke in tongues.
That’s what “initial” means: the first outward sign that this empowerment has happened.
That’s what “physical” means: it’s measurable/observable, not just internal feelings.
And that’s what “evidence” means: not proof that you’re loved by God or saved: but an indicator that the Spirit has baptized and empowered you in a distinct way.
Why Tongues? A Simple Biblical Reason
Tongues can feel like the “weird part” for a lot of people.
So let’s normalize this with a simple thought:
God often gives a tangible sign when He does a powerful work.
In Scripture, God uses outward signs all the time:
Water baptism is an outward sign.
Communion is an outward sign.
Healing is an outward sign.
Prophetic words can be outward signs.
Tongues function similarly: especially in Acts: because it’s a sign that isn’t self-produced.
You can’t “white-knuckle” it.
You receive it.
And it points to something bigger: the Holy Spirit is the One doing the empowering.
The Book of Acts Pattern (Without the Pressure)
Let’s look at the key passages in a clear, non-hyped way.
Acts 2: Pentecost
The Holy Spirit fills the believers.
“And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.” (Acts 2:4)
Result:
tongues
bold witness (Peter preaches)
lives changed (3,000 respond)
Acts 10: Cornelius’ house (Gentiles)
While Peter is still speaking, the Spirit falls.
“For they were hearing them speaking in tongues and extolling God.” (Acts 10:46)
This mattered because it showed God was saving and empowering people from every nation.
Acts 19: Ephesus
Paul lays hands on believers.
“The Holy Spirit came on them, and they began speaking in tongues and prophesying.” (Acts 19:6)
Tongues shows up again as a first sign, and then other gifts follow.
Notice something important:
Acts doesn’t treat tongues as a finish line. It’s the doorway into empowered living.
Tongues vs. Fruit: “Which One Is the Real Evidence?”
This question comes up a lot, and it’s a good one.
Because the New Testament also makes something crystal clear:
The Spirit produces fruit.
Love.
Joy.
Peace.
Patience.
Kindness.
Goodness.
Faithfulness.
Gentleness.
Self-control. (Galatians 5:22–23)
So which is it?
Here’s the simplest way to say it:
Tongues is the initial evidence of Spirit baptism (Acts pattern; AG doctrine).
Fruit is the ongoing evidence of Spirit-filled maturity (Galatians pattern; discipleship).
If someone speaks in tongues but has no growth in love, humility, holiness, and integrity… something is off.
And if someone is growing beautifully in fruit but hasn’t yet received Spirit baptism, we don’t treat them like “less than.”
We encourage them: there’s more empowerment available.
The Spirit is not a trophy.
He’s God’s presence with you: shaping you and sending you.
What Tongues Is (and What It’s Not)
Let’s clear up common confusion.
Tongues is:
A Spirit-given language (known or unknown) expressed through your voice
A prayer and praise language (often private; sometimes public with interpretation)
A sign connected with Spirit baptism in Acts
One of the gifts of the Spirit (1 Corinthians 12), and also a common expression of Spirit baptism (Acts)
Tongues is not:
A measure of your worth
Proof you’re “more spiritual” than others
A replacement for character
A tool to show off
Something you can force by copying sounds
God doesn’t pressure you.
And healthy Spirit-filled ministry doesn’t manipulate you.
What If I Haven’t Spoken in Tongues?
If you love Jesus and you haven’t spoken in tongues, you’re not disqualified from God’s love, presence, or purpose.
Salvation is by faith.
But if you want to receive the baptism in the Holy Spirit, you can ask with confidence.
Jesus said:
“How much more will the heavenly Father give the Holy Spirit to those who ask him!” (Luke 11:13)
A few practical things that help (without making it weird)
1) Start with worship and surrender This isn’t a mental puzzle.
It’s a relational moment.
Tell the Lord you’re open.
2) Ask clearly “Jesus, baptize me in the Holy Spirit. Empower me to be Your witness.”
3) Receive: don’t perform In Acts 2:4, the Spirit gives utterance.
Your role is to yield.
4) Don’t fear losing control The Holy Spirit doesn’t hijack you.
He fills you.
He leads you.
He empowers you.
5) Keep your focus on Jesus The Spirit always points to Christ, not to Himself.
If the moment becomes more about chasing an experience than loving Jesus, reset.
The Purpose: Power for Witness (Even in Quiet Places)
A lot of believers assume “witness” only means standing on a stage.
But Acts 1:8 power meets you in real life:
When you’re exhausted on a night shift and still choosing integrity
When you’re caring for a parent and feel unseen
When you’re isolated due to health limitations
When you’re trying to follow Jesus in a hostile environment
When you need courage to share your faith with a friend
When you need boldness to pray for someone who’s hurting
Spirit baptism is empowerment for mission: public or private, loud or quiet.
And it’s connected with the Church’s larger calling:
The Church is God’s mission in the world.
Healing is provided in Christ’s atonement (we pray and trust God).
The Spirit gives gifts for ministry and building up the body.
We pursue holiness, not to earn salvation, but because we’ve been made new.
We live with hope: Jesus is coming again, and eternity is real.
A Healthy Way to Pursue the Gifts (1 Corinthians 12–14)
The Assemblies of God affirms spiritual gifts are for today, and the Bible gives practical guidelines.
Tongues and interpretation should be practiced in a way that builds up the church and reflects God’s character: orderly, loving, and Christ-centered.
A few simple guardrails:
Love leads. Gifts without love miss the point (1 Corinthians 13).
Edification matters. Spiritual gifts are for strengthening people, not impressing them.
Scripture stays central. The Spirit never contradicts the Word He inspired.
Jesus stays famous. If a gift draws attention away from Christ, it needs correction.
“Evidence of the Spirit” in Everyday Life
If you’re looking for signs the Holy Spirit is truly at work in you, here are a few that often show up alongside Spirit baptism and Spirit-filled living:
A growing love for Jesus and His Word
Conviction that leads to repentance (not shame spirals)
New boldness to share your faith
Greater compassion for people far from God
More sensitivity to the Spirit’s leading
Increasing spiritual fruit over time
A desire to worship
A deeper hunger to pray: even when life is busy
Tongues can be the initial evidence of Spirit baptism.
But the Spirit’s work doesn’t stop there.
He’s forming Christ in you and empowering Christ through you.
Want to Go Deeper (Without Getting Overwhelmed)?
If you’re newer to faith or just want a clear foundation, keep it simple:
Read Acts 1–2, then Acts 10, then Acts 19
Read 1 Corinthians 12–14 slowly
Ask God to make His Word come alive

A Simple Prayer to Ask for the Baptism in the Holy Spirit
Jesus, I belong to You.
Thank You for saving me and making me new.
I ask You to baptize me in the Holy Spirit.
Fill me with Your power so I can be Your witness.
I surrender my fears, my pride, and my need to control.
Holy Spirit, I welcome You: lead me, empower me, and help me live like Jesus.
Amen.
