The Bible does not tell us whether or not we will all speak one language in heaven. Therefore, we can only talk about what might happen in heaven regarding communication. There are more than 2000 languages on earth today. Will God give us the ability to understand all 2000 languages simultaneously? Or does it make more sense to say that there will be a new or old heavenly language? It would seem that the best way to communicate would be with one language, not many. Perhaps it will be the original language of Genesis 3, where God spoke with Adam and Eve. But it does not say what language it was.
Languages of Angels
Apparently, there are angelic languages. “If I speak with the tongues of men and of angels, but do not have love, I have become a noisy gong or a clanging cymbal” (1 Cor. 13:1). So we can ask if the tongues of angels are the same language God used in the garden of Eden. But again, there is no way to know. Nevertheless, language is something God uses to communicate with us. It is one of the characteristics of being human to be able to communicate. So, it makes sense that there will be at least one common language. So, we can’t say for sure.
Near Death Experiences
Some people who have had near-death experiences and claim to have gone to heaven have stated that they were able to communicate not just by spoken word but by thought. Now, normally, I would not cite something as debatable as near-death experiences, but it appears that Paul wrote of one in Scripture.
2 Cor. 12:2–4, “I know a man in Christ who fourteen years ago—whether in the body I do not know, or out of the body I do not know, God knows—such a man was caught up to the third heaven. 3 And I know how such a man— whether in the body or apart from the body I do not know, God knows— 4 was caught up into Paradise and heard inexpressible words, which a man is not permitted to speak.”
So you can take it or leave it. But, since there is an apparent NDE in Scripture, we cannot outright negate all people’s near-death experiences and what they said about communicating in heaven.
Conclusion
We cannot definitively say we will all speak one language in heaven. It would make sense to assume that we will. But again, we just don’t know. Nevertheless, God is not a God of confusion (1 Cor. 14:33), so there will be some way that we communicate with each other with clarity. We’ll just have to trust that God will take care of it when we get there.
