In the law it is written: “With men of other tongues and other lips I will speak to this people; And yet, for all that, they will not hear Me,” says the Lord.
In the law it is written:
The “law” refers to a free Old Testament quotation from Isaiah 28:11-12. The “law,” then, is Scripture. The context of Isaiah 28 is Judah’s refusal to accept Isaiah’s warning about the coming Assyrian invasion. About 15 years before Isaiah made this prophecy, the Assyrians (722 B.C.) conquered the northern kingdom of Israel. Isaiah then warned the southern kingdom Judah to repent, but Judah refused to take heed to Isaiah’s warning, so God sent foreigners speaking the Assyrian language.
“With men of other tongues and other lips (Assyrian invaders into Judah)
The words “other tongues” clearly refer to the Assyrian language, a known real language of Isaiah’s day (2 Kg 18:26). First Corinthians 14 clearly refers to real, known languages as Acts 2 refers to real languages and even names the languages and dialects (Acts 2:7-11).
I will speak to this people (the Jews of Isaiah 28);
“This people” is Judah in Isaiah’s day; that is, Jews.
And yet, for all that, they will not hear Me,”
Yet, with all that, Judah remained in negative volition to Isaiah’s message. One hundred years later, the Babylonians invaded Jerusalem speaking the Assyrian language.
says the Lord.
This is what the Lord said in the book of Isaiah.
Some people remain in negative volition even if God speaks to them directly.
It does not make any difference whether God speaks directly to some people because they remain in their negative volition. A person convinced against their will is of the same opinion still. Jesus said the reason for this is that men love darkness rather than light because of their sin:
John 3:19, And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
