I've seen a few dotting the landscape mostly rural communities, but I can't really say that I have ever drank from one---a well, that is. As a city dweller, I'm so used to getting water from a protected, chlorinated supply that is conveniently piped into my home. So glad I don't have to go outside in all kinds of weather to drop a bucket down a hole in the ground. As for which is better--well vs tap-- I've heard that well water tastes better; and may even be better for you. But regardless of where it comes from no one would argue that water is essential to life. Makes me wonder if that's what God had that in mind when he created the seas first and had them cover two-thirds of the earth's surface. And even though he created man from the dust, our bodies are composed of 60 per cent water; some organs, like the brain, are as much as 90 per cent water.
Besides being a necessity for life, water can kill. People have drowned in it. Whole communities like New Orleans, La. and Johnstown, Pa. have been flooded by it. Wars have been fought over it (water rights). The BP oil disaster demonstrated how reckless pollution of our waters can devastate both human and animal species. Our dependence on water for survival is universal for human and animal kind alike. Even if we journey into outer space to explore other life forms, the first thing that astronauts look for is whether there is a sustainable water source on the planet.
Jesus often used water as a metaphor for spiritual things. The Holy Spirit is often referred to as "living water" freely given to those who ask (John 4:10). The Bible speaks of water to illustrate the purifying effect of God's Word in making us holy "by the washing of water through the word (Eph 5:26). By contrast, a church that doesn't preach the Word of God, and a people that won't heed and obey God's Word are a dirty bunch---carnal and undisciplined. Who complains of thirst, and then, when a glass of water is set before him, just stares at it? In the same way, Jesus offers sinners "living water" but to enjoy its benefits, we must come to the source and drink freely. Are you thirsty?
