Lord’s Library editors offer an Isaiah 55:11 meaning with commentary and supporting Scriptures for your edification.

Isaiah 55:11 showcases the power and purpose of God’s Word. It also shows us that one’s actions, no matter how small or seemingly insignificant, when done for the Lord, serve their intended purpose. See verse: “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.” As we can see, this Scripture emphasizes the effectiveness of God’s Word in fulfilling His perfect will.

The power of God’s Word is reiterated throughout Scripture. See Hebrews 4:12: “For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.”

This underscores the idea that God’s Word is not only effective but also transformative. It penetrates the deepest parts of the human heart, bringing conviction, correction, and guidance to those with ears to hear. See Matthew 11:15: “He that hath ears to hear, let him hear.”

The Gospel

Isaiah 55:11 Meaning


The assurance that God’s Word will not return void is a promise that His plans and purposes will prevail. In this we can have unending confidence. In Numbers 23:19, we read: “God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?”

This reinforces the truth that God’s Word is always reliable. When He speaks, it will come to pass, whether in creation, as seen in Genesis 1, or in His promises and prophecies.

Isaiah 55:11 also aligns with Romans 10:17, which declares: “So then faith cometh by hearing, and hearing by the word of God.” This Scripture is pivotal in understanding the process of coming to the Christian faith. Faith is not automatically present in individuals; rather, it is something that grows within a person through the act of hearing the Word of God.

Simply put: God’s Word is the foundation for faith, and as it goes forth, it accomplishes the work of building faith in those who hear and receive it.

Isaiah 55:11 reminds believers of the absolute sovereignty of God’s Word. It affirms that His promises are sure, His plans are unfailing, and His Word is the very agent by which His will is done on earth. Editor’s note: Amen!
