Here are 7 Bible verses about water with a commentary about their meaning.
John 4:14 “But whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.”
We cannot survive without water and the water that Jesus was talking about wasn’t the kind of water that will satisfy for only a few hours or so. This water satisfies for all time. This spring of water wells “up to eternal life” and He is the only source of that living water (Acts 4:12).
Ephesians 5:25-27 “Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish.”
At the end of Ephesians chapter five, Paul was writing about God’s expectations for husbands and wives toward one another and in the verses above he gives the analogy of Christ giving Himself up for her, which is the church, as He is the Bridegroom and the church His betrothed wife, and He cleansed her by the washing of the water of the Word. Paul refers to the Word of God, which is also another name for Jesus (John 1:1, 14), as water and the Word washes us just like water washes us or cleanses us. The water of the Word purifies us by what we find in the Word of God. It is no surprise then that Peter refers to the so-called “words of life” (John 6:68) as those words spoken by Jesus.
Isaiah 12:3-4a “With joy you will draw water from the wells of salvation. And you will say in that day.”
Next to the Book of Genesis, the Book of Isaiah mentions water more than any other book in the Bible and the most common reference to water is the same one that Jesus refers to it and that is in the context of salvation. Water is a great analogy of eternal life as water makes physical life possible while “the wells of salvation” make eternal life  possible and this is most certainly the context in which Isaiah writes because verses 3 and 4 are preceded by his writing that “the Lord God is my strength and my song, and he has become my salvation” (Isaiah 12:2).
John 7:37-38 “On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.”
The Apostle John refers to water almost three times as much as the next author of any book in the New Testament. John writes about the “living water” again that will flow “out of his heart” for all who believe in Christ for “if anyone thirsts let him (or her) come to me and drink” says Jesus.
Jeremiah 17:8 “He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit.”
Once more the symbolism of water and life come together and in this analytical writing, Jeremiah writes about the deliverance of Israel which can be likened to that of a sinner. Whoever is planted by the water has their roots in the streams of living water (reminiscent of Jesus’ words in John 4 and 7 and also in Isaiah 12). When the heat comes there is no anxiety in times of drought (leanness or trials) for they will not cease bearing fruit. So it is with those who drink from the living waters of faith in Christ.
Joel 3:18 “And in that day the mountains shall drip sweet wine, and the hills shall flow with milk, and all the streambeds of Judah shall flow with water; and a fountain shall come forth from the house of the Lord and water the Valley of Shittim.”
This glorious verse and chapter speak of the coming kingdom when all will be satisfied and there shall be an abundance of all things necessary for life. This water or fountain that flows “forth from the house of the Lord” closely resembles that of the New Jerusalem which you can read about in Revelation 22:1 where “the river of the water of life, bright as crystal, flowing from the throne of God and of the Lamb.”
Revelation 7:17 “For the Lamb in the midst of the throne will be their shepherd, and he will guide them to springs of living water, and God will wipe away every tear from their eyes.”
This is after the Lord returns and much like Jesus speaking to the Samaritan woman at the well, the springs of living water all flow from Christ for He alone gives life and the only water that will be wiped away will be those tears from the eyes of the saints as it says in Revelation 21:4 “He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”
Jesus proclaims “I am the Alpha and the Omega, the Beginning and the End. To the thirsty I will give water without cost from the spring of the water of life” (Rev 21:6) and it is free to drink but it cost Jesus His very life. Are you thirsty? Come to the fountain  and drink for everlasting life.
