After prophesying about the coming Messiah, The Word of the Lord came down in Isaiah 51
to give comfort.
God said, listen all that live righteous, all that seek the Lord: Look at where you came from. Look to father Abraham and Sarah, how that God called them alone, blessed him, and increased his wealth.
The Lord said he would comfort Zion. All the places laid in waste will be comforted, and and her desolate wilderness will be made like the garden of Eden. Joy and gladness will be found within, thanksgiving and singing.
God said that a law would be given, and His judgment would rest as a light for the people. When His righteousness comes, His salvation will go forth. His arms will judge the people, and those same arms giving judgement will be the arms of trust for the people.
He said to look at the heavens, and look to the earth beneath your feet. Those things will vanish and pass away, and those that dwell therein will die in the same manner. But His salvation will last forever, and His righteousness will not fail.
God said listen all that know righteousness, the people that keep the law in their hearts: Do not fear to be accused by men, and do not be afraid of their condemnation. The moths will eat them like an old robe. The worm will eat them like wool. But God's righteousness will be forever, and His salvation will be for all generations.
He said to awake, and put on strength. He called them the "arm of the Lord," and asked them to awake as they did in the ancient generations of old. That same arm cut Rahab and wounded the dragon. That same arm dried the sea for the children of Israel to pass over.
Therefore, the redeemed shall return with singing unto Zion. Everlasting joy will be flowing from them. They will have great joy and all sorrow will pass.
God said, "I, even I, am he that comforteth you." He asked who were they to be afraid of any man who is destined to die? How were they to be afraid of a man who would one day be made as the grass of the ground? Who were they to be afraid of a man who forgot the Lord, his own Maker? Where is their fury?
God said, "I am the Lord thy God, that divided the sea, whose waves roared: The Lord of hosts is his name." He said that He was the one that put words in their mouth, and covered them with the shadow of his hand to plant the heavens and lay the foundations.
They were His people.
As Christians, we should ask ourselves: Do we find comfort in the Word of God? When others come against us, do we stand in God's Word? Do we not realize that God will send comfort to us? Do we take comfort in knowing that heaven and earth will pass away, but God's salvation will last forever? When God plants his words in our mouths, do we speak them or do we hide them from others? Are we His people?
