Brackish

Can both fresh water and salt water flow from the same spring? — James 3:11

James's question is metaphorical. Can blessing and cursing come from the same mouth? Maybe the unexpected answer is yes if the spring is contaminated. And salty water is deadly to drink.

Filtering what comes out is harder work than monitoring what goes in. We're told, "Above all else, guard your heart, for everything you do flows from it." (Prov. 4:23)

Sneeze

Some, like Alan Hirsch, have compared disciple-making to a sneeze. When the explosive message that Jesus is Lord reaches the right host, Kingdom life can take hold and maybe spread virally. It helps when people's resistance is low and they haven't been inoculated with a false gospel.

Qualitatively Speaking

In our culture, we prioritize quantitative over qualitative. We like things to be measurable, definitive, binary. This is what we do with eternal life. Heaven or hell. Starting at the point of physical death and reaching forward. But, Biblically, eternal life is eternal in both directions. It's a river of life with the Triune God that has always been, and always will be, love. It's knowing God. We're invited into that life now. It's an eternal kind of life. A quality of life that just happens to have an immeasurable quantity.
