To answer you directly, there are no bible verses that say that all beings in heaven will speak the same language. There are only 1 bible verses that I can think of that speaks of heavenly languages
1 Corinthians 13:1
13 If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.
After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!”
Revelation 7:9-10

I hope this answers your question.
@elmer O i c. This is the only verse that ever talks about out language when we in heaven?
Posted by: @charlieWhats the language going to be when we get there? Also how are we going settle there?
Also, I am sure our time on heaven, is different from on earth. So if we are in heaven, wouldn't we be time traveling? They say in the bible that heaven is eternal, while on earth we just live physically time passing by. So is heaven like a big time machine?
@elmer Elmer, may I ask you. Are you the pastors son? Or have you been educated on your own about God and the bible?
