Amplified Bible, Classic Edition
5 Then the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped.
6 Then shall the lame man leap like a hart, and the tongue of the dumb shall sing for joy. For waters shall break forth in the wilderness and streams in the desert.
7 And the burning sand and the mirage shall become a pool, and the thirsty ground springs of water; in the haunt of jackals, where they lay resting, shall be grass with reeds and rushes.
This was fulfilled at the coming of the Messiah the first time. When Jesus came and ministered, His ministry was marked by physical healing and restoration. Everything Jesus did throughout His ministry pointed to Him as the Messiah. When John sent disciples to Jesus to inquire if Jesus was truly the Messiah or should they look for someone else. Jesus responded with “So He replied to them, Go and tell John what you have seen and heard: the blind receive their sight, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised up, and the poor have the good news (the Gospel) preached to them” (Luke 7:22). Jesus' answer to John was quoted from this passage in Isaiah. Jesus was stating beyond a shadow of a doubt through His actions and His words that He is indeed the Messiah, The Christ, The Anointed One.
Water is often a symbol of the Holy Spirit, refreshing, and renewal. Jesus' ministry was marked by the power of the Holy Spirit. In everything Jesus did He was led and guided by the Holy Spirit. Throughout His ministry He healed those who were lame and those who were unable to speak. John wrote at the end of his gospel that if all the things that Jesus did were written down, there would not be enough books to contain them (John 21:25).
Throughout the gospels the miracles by Jesus that are included are done so for a reason. Each of the gospel writers had a specific audience they were writing to and they had a specific and unique purpose why they were writing. But through Jesus' ministry we see that everything He did showed that He is the Messiah. When He returns to the earth and establishes His kingdom it will truly be a time of renewal and refreshing. It will be a time of perfect peace and truly waters shall break forth in the wilderness.
We have more language that points to a time of refreshing and renewal. The Lord says the burning sand and the mirage shall become a pool. The thirsty ground springs of water. In the haunts of jackals shall be grass with reeds and rushes. This is all a picture of things that have been desolated by the judgement of God and have been restored at the coming of the Messiah. The people of Israel suffered the correction of God because of their rebellion and sin. The nations of the world will experience the judgement of God because of their rebellion and wickedness. But there is coming a day when our Savior shall return and establish His kingdom upon the earth. May our hearts never be fixed upon this world and the things of this world, may our hearts be fixed upon Christ alone.
