Isaiah 55:11

So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper [in the thing] whereto I sent it.

So shall my word {H1697} be that goeth forth {H3318} out of my mouth {H6310}: it shall not return {H7725} unto me void {H7387}, but it shall accomplish {H6213} that which I please {H2654}, and it shall prosper {H6743} in the thing whereto I sent {H7971} it.

so is my word that goes out from my mouth - it will not return to me unfulfilled; but it will accomplish what I intend, and cause to succeed what I sent it to do."

so My word that proceeds from My mouth will not return to Me empty, but it will accomplish what I please, and it will prosper where I send it.

so shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.

Commentary

Isaiah 55:11 is a powerful declaration of God's unwavering faithfulness and the absolute efficacy of His divine word. This verse assures us that whatever God speaks, whether a promise, a command, or a prophecy, will inevitably come to pass and achieve its intended purpose.

Context

This verse is nestled within Isaiah chapter 55, a profound invitation from God to His people. The chapter opens with an offer of spiritual nourishment and satisfaction to those who are spiritually hungry and thirsty (Isaiah 55:1). It transitions into a call to seek the Lord and an assurance of His abundant pardon (Isaiah 55:6-7). Crucially, it precedes with the declaration that God's thoughts and ways are infinitely higher than human thoughts and ways (Isaiah 55:8-9). Immediately preceding verse 11 is the analogy of rain and snow descending from heaven, watering the earth, and producing fruit, which perfectly illustrates the unstoppable and productive nature of God's word (Isaiah 55:10). Isaiah 55:11 then draws a direct parallel, affirming that just as natural elements fulfill their God-given purpose, so too does His spoken word.

Key Themes

  • The Efficacy and Power of God's Word: The central message is that God's word is not idle or ineffective. It possesses inherent power to accomplish exactly what God intends. This echoes the creative power of God's word in creation and its living and active nature described in the New Testament.
  • Divine Purpose and Sovereignty: God's word is always sent with a specific purpose, and it will unfailingly achieve that purpose. This highlights God's absolute control and sovereignty over all things, including the fulfillment of His plans.
  • Reliability of God's Promises: This verse serves as a powerful guarantee for all of God's promises and prophecies. It assures believers that what God says, He will do. It reinforces the truth that God is not a man that He should lie, and His word will never return to Him unfulfilled.

Linguistic Insights

  • "Void" (Hebrew: רֵיק - req): This word signifies empty, useless, without effect, or without purpose. When God's word "shall not return unto me void," it means it will not come back to Him having failed to accomplish its mission. It won't be like a messenger returning without having delivered the message or achieved the objective.
  • "Prosper" (Hebrew: צָלַח - tsalach): This term means to succeed, advance, be profitable, or accomplish successfully. It indicates not just fulfillment, but successful, effective execution of the divine will. The KJV's "in the thing whereto I sent it" emphasizes the precision of its success according to God's specific intention.

Practical Application

Isaiah 55:11 offers immense comfort and challenge for a general audience:

  • Trust in God's Promises: In times of doubt, difficulty, or waiting, this verse reminds us that God's promises are absolutely reliable. If God has spoken it, it will come to pass. This applies to promises of salvation, provision, guidance, and His ultimate plan for humanity.
  • Confidence in Sharing the Gospel: For those who share the Christian faith, this verse encourages confidence in proclaiming God's word. The message of salvation, repentance, and hope in Christ carries divine power and will not return void; it will accomplish God's purpose in the hearts of those who hear it.
  • Endurance in Prayer: When praying according to God's will and His revealed word, we can have assurance that our prayers aligned with His purposes will be effective, because His word is effective.
  • Hope for the Future: This promise extends to all of God's prophetic words concerning the future, including the promise of a new heaven and new earth and the enduring nature of His truth. What God has declared will happen.

This verse is a cornerstone for understanding the nature of God's communication with humanity: it is always active, purposeful, and infallibly effective.
