Is speaking in tongues a proof of the baptism in the Spirit?
Yes. When the Spirit fell on Cornelius' house, the Jewish believers knew it was real for one reason: "they heard them speaking in tongues and praising God" (Acts 10:46). The tongues were the proof. That astonished Peter and his friends into accepting that God had received the Gentiles too.
Let me be precise about what I am and am not saying, because this is where people tie themselves in knots. Speaking in tongues is proof that you are baptized in the Spirit. I am not saying the reverse — that not speaking in tongues proves you are not. Those are different statements, and only the first is safe. So I state the positive and leave the negative alone unless someone asks, because the moment you try to prove you are Spirit-baptized without the sign, you have very little to point to. Better to seek the gift than to argue about its absence.
Is it necessary? Is it for everyone?
God "does not show favoritism" (Rom. 2:11). So it would be strange indeed if this were reserved for a special few. People who speak in tongues are not better than people who don't — no more than a saved person is better than a lost one; both are saved only by grace (Eph. 2:8-9). But those who pray in the Spirit do have access to something: they are "building yourselves up in your most holy faith and praying in the Holy Spirit" (Jude 20). God will not withhold from you something you need to serve Him.
So put the two honest questions side by side:
- Do all speak in tongues? No. Paul asks it directly — "Do all speak in tongues?" (1 Cor. 12:30) — and the answer built into the question is no.
- Should all? Yes, preferably. Paul also says, "I would like every one of you to speak in tongues" (1 Cor. 14:5).
Those are not a contradiction. One is a fact; the other is God's preference. It is the same shape as healing: are all healed? No. Should all be healed, preferably? Yes. God's heart and the fallen world's reality are not always the same size yet.
And I will be honest with you here, from experience, because this is exactly where honesty matters most. I have prayed for people with cancer and watched God heal them. And my own mother died of cancer.
She was no stranger to sickness — asthma plagued her for most of her adult life. We children knew the hospital so well that we treated its basement corridors as a playground. And this was no family without faith: my own grandfather was a known healing evangelist who had seen many strong miracles. Still the asthma stayed.
Near the end, alongside the cancer, she developed pneumonia; between that, the chemo, and the asthma, it was grave. My father called me and made very clear how serious it was. The next day I went with a friend to the hospital to pray for her — and found her sitting up in bed, talking and joking, seeming almost well. I could not hide my surprise, so I asked her about it. She told me that the night before she had seen a vision: on the wall, written in blood, were the words "Your name is in the Lamb's book of life." The moment she saw it, she was healed of the pneumonia. The asthma and the cancer remained, and in time they took her.
And here is the thing I most want you to hear, because it is easy to walk away from a story like that quietly blaming God. Don't. After she died I sat with it, and over time I found perhaps ten different reasons, each one theologically possible, for why the healing did not come — and not one of them laid the blame at God's feet. My trouble was never a shortage of explanations. It was that to know which one was the true one, I would have to be omniscient, and I am not. So I stopped forcing an answer and let it lie.
Hear what I am not saying. I am not saying God took her, or refused her, or that her faith or mine came up short. The disease killed her; God did not author it. Even Paul, who healed crowds, left his co-worker Trophimus sick (2 Tim. 4:20). "Preferably" has to be big enough to hold both the healings I have seen with my own eyes and the grave I have stood beside — without ever laying that grave at God's feet. Anyone who tells you healing is always instant, always everyone, or always someone's lack of faith is not telling you the truth, neither of Scripture nor of the life I have lived.
I tell you the hard part plainly so you will trust me on the sure part. Because unlike the mystery of why one person is healed and another is not, how you receive the Spirit holds no mystery at all. Jesus made it as plain as He ever made anything:
"How much more will your Father in heaven give the Holy Spirit to those who ask him!" — Luke 11:13
You ask. And your Father, who is good, gives.
In short: Tongues is a proof of the baptism in the Spirit — the positive proof; don't twist it into the negative. It is for everyone, because God plays no favorites, even though not everyone will speak in tongues. Do all? No. Should all, preferably? Yes — the same way God wants all to be healed in a world where not all are yet. Ask the Father; He gives good gifts.
