Isaiah 40:21
“Have ye not known? have ye not heard? hath it not been told you from the beginning? have ye not understood from the foundations of the earth?”
King James Version (KJV)
Read this verse in context with translation switching:
Read Full Chapter →God's greatness has been evident since creation itself; the exiles should have remembered and understood.
Context
The prophet shifts from attacking idolatry to calling the exiles to recollection. They have the testimony of creation, the stories of their forefathers, the witness of generations. Despair has made them forget what they should have always known.
What Does Isaiah 40:21 Mean?
Four rhetorical questions build in force, accusatory and yet inviting. Isaiah appeals to what should be obvious and known. Have you never looked at the world and sensed the presence of God? Have the stories not been told to you, passed from parent to child? Have the very foundations of the earth not spoken of God's power and care? The exiles stand in a long tradition of knowledge reaching back to the beginning of time. Yet they have chosen to forget, to ignore what was always there to teach them. The tone is not gentle rebuke but a call to wake up, to remember what they have known all along.
Here we recognize the God revealed in Jesus, who embodies the wisdom evident since creation. The Word through whom all things were made (John 1) was present at the foundations of the earth, and that same Word became flesh to dwell among us. Jesus does not introduce a new God; he reveals the God who has always been God, inviting us into remembrance and new understanding.
Application
When we face difficulty or loss, we often forget the God we have known all along. Isaiah calls us to remember. What have we seen of God's power, faithfulness, and provision? What stories from Scripture and from our own lives testify to his presence? We can ground our hope not in new revelations but in remembering what has always been true.
