We can answer a question that you may not have realized needed to be asked: what's the difference between water of life and normal water? Is there a chemical difference, or is this intended as a metaphor?
Water of Life
We Reap What We Sow
Reaping what we sow as bitter consequences for bad decisions is caused by misrepresenting God and leading people astray with false teachings. Jeremiah made this charge against false prophets in his time.
Gall as an Effect
Gall as an effect is bitter consequences that we have to endure. The cause may take the form of immorality, idolatry or any other sin. The consequences are widespread and affect whole communities.
Gall as a Cause
Gall can be brazen boldness coupled with impudent assurance and insolence. Someone heard the Bible being preached but decided that they're immune. Their attitude was that it's irrelevant and doesn't refer to them.
The Essence of Free Will
Water is the essence of free will which is why God used it as the raw material for the universe. God's goal was to create sentient life that had the ability to accept or reject Him as creator based on the testimony of the creation itself.
Where Did the Deep Come From?
People seem genuinely surprised when we point out to them that, according to the Bible, there was a body of water present before creation. It's was the deep.
Deducing the Deep
God as the Holy Trinity existed with a formless mass of water in darkness, but they weren't the only ones present. There are passages in the Bible that make it clear that God had already created all human souls.
A Pure River of the Water of Life
If we're going to live with the Lord God who's going to reign forever and ever, and a pure river of the water of life is flowing, then it must be cycling because God isn't going to constantly create new water forever.
Deep Calls to Deep
We're going to ignore the possibility that Psalms 42:7 is flowery poetic language intended to teach us something spiritual. Instead we're going to use it as the description of a hydrological system in a test of Hypothesis 22.
The Great Deep
The deep and the great deep are both translated from the same Hebrew word, tehom. The difference signifies a transition from the deep where Earth was created to when the great deep is in the interior of the Earth.
