To Bible loving people of all denominations Jesus/God is the truth, so saying that truth will prevail is the same as saying God will prevail.
[QUOTE=Prov 12:19]
Truthful lips endure forever, but a lying tongue lasts only a moment.

Is the closest I can find directly, which to me does answer the OP’s question, yes it’s there.
One can get it indirectly, such as:
[QUOTE= Is 57:17]
no weapon forged against you will prevail,
and you will refute every tongue that accuses you.
This is the heritage of the servants of the Lord,
and this is their vindication from me,”
declares the Lord.

But it is in context of a believer.
Also
[QUOTE= John 8]
31 To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples. 32 Then you will know the truth, and the truth will set you free.”
[/QUOTE]
Speaking of the disciples who will overcome the illusion of the world and achieve to use a Buddhist term enlightenment.
And other stuff such as it is the Lord’s will that will prevail, not man’s plans and schemes.
Already covered somewhat below, but that is ‘all **Protestant **Bibles’, Catholics (and apparently Anglicans) still include them.
