Isaiah 12:4

What is the background to, and meaning of, Isaiah 12:4?

I first published this commentary on Quora on 25 January 2019. This version may have minor edits.

Short Answer

4 And in that day you will say,

“Give thanks to the LORD, call on His name.
 Make known His deeds among the peoples;
 Make them remember that His name is exalted.”

The verse promises complete security to people of a future age who will have placed their trust entirely in God and His works. Although the verse does not apply to this age, the principle behind it is universal. In this age, those who place their trust entirely in God and His works are promised emotional peace, but not the physical victories indicated by the context of Isaiah 26:3. To teach the promise of peace to people of our times, careful teachers will use other verses.

Background

During Isaiah’s time, Israel had been split in two. The northern segment, “Israel,” had been conquered, and its survivors had been carried off to other lands. The southern segment, “Judah,” remained but was overtaken with other religions and corruption. Followers of God not only received mistreatment from their own neighbors, but also saw the same thing that had happened to Israel threatening to happen to Judah.

Those who listened to the prophets knew that God’s punishment was coming. At this time, prophets such as Isaiah not only foretold about the punishment, but also foretold that God would restore their people to Judea. Such promises were accompanied by other details. Such details described a savior who would save not only their people, but all who would turn to Him.

So the prophesies not only warned of judgment, but also promised hope.

These prophesied events came like twin mountain tops lined up in the distance. The hearers could not tell them apart. That is one reason the Jews rejected Christ. They wanted the Second Coming to establish their national independence and dominance.

But from our position between the two peaks, it’s easy to see the difference. One mountain top was the incarnation of God the Son. The other was a Second Coming. During the first coming, Messiah would provide redemption through faith in His suffering; whereas during the second coming, He would assert His authority, judge the wicked, and establish peace on earth.

Isaiah 12:1 and 4 go together, but to appreciate their meaning, we have to place them in context. Verse 1 begins, Then you will say on that day… and verse 4 begins And in that day you will say…. So we need to turn to the previous chapter to determine when “that day” is.

Chapter 10 describes judgement and destruction of Judea. Chapter 11 describes Messiah as a descendant of Jesse, King David’s father. The chapter opens by describing His character and segues into describing His work during His Second Coming. It is here that we find beautiful images such as

And the wolf will dwell with the lamb,
And the leopard will lie down with the young goat,
And the calf and the young lion and the fatling together;
And a little boy will lead them. (verse 6)

In that time, the earth will be full of the knowledge of the LORD… The nations will resort to [Messiah] (verses 9 and 10). In other words, faith in God would no longer be a parochial religion of the Jews, but a faith among all peoples.

The remainder of the chapter describes the final restoration of Israel and judgement of its enemies.

Meaning

In this context, now we can appreciate chapter 12.

Then you [the believer] will say on that day,
“I will give thanks to You, O LORD;
For although You were angry with me,
Your anger is turned away,
And You comfort me.

“Behold, God is my salvation,
I will trust and not be afraid;
For the LORD GOD
is my strength and song,
And He has become my salvation.” (verses 1–2)

This could be interpreted either of two ways. The obvious application is that, in the time of Messiah’s Second Coming, God will have forgiven Israel for its blasphemies and crimes. A second meaning comes from the principle described, namely, that there is a relationship between trusting God for salvation and having His justice satisfied. The personal language indicates that the quotations are spoken by individuals and not as a collective nation.

This relationship of redemption and trust allows verse 3: Therefore you [the believer] will joyously draw water from the springs of salvation.. Water represents the cleansing and strength provided by God through this new relationship with Him.

In verse 4,

And in that day you [the redeemed] will say,
“Give thanks to the LORD, call on His name.
Make known His deeds among the peoples;
Make them remember that His name is exalted.”

So in verses 1–2, we have believers rejoicing and praising God, and in verse 4, they encourage each other to praise God and share the good news. They will do so, motivated by thankful hearts described in verses 1–2.

If we apply verses 1–4 to ourselves, it is about the attitude that we should have toward God; and it should have such a magnitude and outworking that we want everybody to share in the same joy. There is no room for “practicing your religion at home” or “freedom from religion.” There should be great joy in salvation, and you should want to shout it from the housetops! (Alas, we are not in the age of the Second Coming yet, and our bodies do not always allow our experience to match up with theory.)

There is one more important implication in this passage. In order for “you,” a believer over 700 years before Messiah’s first coming, to give thanks to God when Messiah returns in 2019+ AD, “you” must be alive and present. This is not an unusual inference. See Mark 12:18–27. Resurrection is implied in the Old Testament and explicitly promised in the New Testament.

I’m sure there are some who will pluck the verse and twist it into some other meaning. Remember this:

If the plain sense makes good sense,
any other sense is probably nonsense.
