What does Isaiah 48:6 mean?
What is the meaning of Isaiah 48:6?

You have heard these things

“ You have heard these things ” (Isaiah 48:6) points back to the prophecies God had already spoken and fulfilled.

• Earlier in the chapter, the Lord reminds Israel, “I foretold the former things long ago; they came out of My mouth; I proclaimed them. Suddenly I acted, and they came to pass” (Isaiah 48:3).

• Just as Moses said, “From heaven He let you hear His voice to discipline you” (Deuteronomy 4:36), the people had been given ample revelation.

• God’s faithfulness to His word distinguishes Him from idols (Isaiah 44:7–8) and underlines the expectation that His people should remember what they have already received.


Look at them all

“ Look at them all ” calls for deliberate reflection on the evidence.

• Miracles like the Red Sea crossing (Exodus 14:31) and the conquest of Canaan (Joshua 23:14) stand as tangible proof that every promise God makes, He keeps.

Psalm 111:2 affirms, “Great are the works of the LORD; they are pondered by all who delight in them.” Israel is urged to review the catalog of fulfilled promises and see God’s hand.

• This principle endures for believers today: track God’s past faithfulness to bolster present trust.


Will you not acknowledge them?

“ Will you not acknowledge them? ” confronts stubborn hearts.

• Despite undeniable evidence, Israel resisted admitting God’s sovereignty—much like later generations who, though seeing Jesus’ miracles, still “did not believe in Him” (John 12:37).

Romans 1:21 describes the same refusal: “Although they knew God, they neither glorified Him as God nor gave thanks.”

• The verse presses for confession—agreeing with God about what He has done and who He is.


From now on I will tell you of new things

With the past record established, the Lord moves forward: “From now on I will tell you of new things.”

Isaiah 42:9 echoes this pledge: “Behold, the former things have happened, and now I declare new things; before they spring forth I announce them to you.”

• Immediately, that “new thing” included the rise of Cyrus who would free the exiles (Isaiah 45:1–4)—a prophecy given 150 years in advance.

• Ultimately, the promise stretches to the greater deliverance accomplished by the Messiah (Isaiah 52:13–53:12), showing that God’s revelation is progressive yet always rooted in His unchanging character.


Hidden things unknown to you

God adds, “hidden things unknown to you.”

Deuteronomy 29:29 reminds us, “The hidden things belong to the LORD our God, but the revealed things belong to us.” Here, God graciously moves some truths from the hidden category into the revealed.

Jeremiah 33:3 offers the same assurance: “Call to Me and I will answer and show you great and unsearchable things you do not know.”

• For the New Testament believer, 1 Corinthians 2:9–10 affirms that the Spirit now uncovers what eye has not seen nor ear heard. God delights to draw His people deeper into His purposes when they humble themselves and listen.


summary

Isaiah 48:6 is a divine wake-up call. God reminds Israel that they have already heard and seen His faithfulness, urges them to examine the evidence, confronts their reluctance to admit the truth, and then graciously promises fresh revelation—some of it long concealed. The verse challenges every generation to remember what God has done, acknowledge His sovereignty, and stay attentive as He unveils the next chapter of His redemptive plan.
