Mark 9:50 (ESV)
Salt is good, but if the salt has lost its saltiness, how will you make it salty again? Have salt in yourselves, and be at peace with one another."
Salt is good. Tell that to your dietician. Who you going to believe some quack or Jesus? Personally I go with Jesus. But that’s because I like salt… I didn’t really need him to tell me it was good. Food without salt is tasteless. Salt brings out flavor. But if it loses its saltiness…
Have salt in yourselves, and be at peace with one another. To have salt in yourself is to be at peace with others, forgiving them. So how does the salt regain its saltiness? Simple, God restores it. This he does for you when he forgives you your sin.
