You and I both know many things that seem good for a while, even though they aren’t biblical. Has not God been faithful and longsuffering and patient with us in spite of our woeful ignorance and lack? Someone dying of thirst may perhaps get some sustenance from a polluted stream, but if he continues to drink from it he will die. Instead, we have the crystal clear river of life.
"And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb."
