Jesus went on: “It’s what comes out of a person that pollutes: obscenities, lusts, thefts, murders, adulteries, greed, depravity, deceptive dealings, carousing, mean looks, slander, arrogance, foolishness—all these are vomit from the heart. There is the source of your pollution.”
(Mark 7:20-23 MSG)
A doctor diagnoses physical disease by examining the vile bodily discharges that come from within a person. The Lord diagnoses soul sickness by examining the sinful behaviors that flow from our hearts. The cure is only one prayer away by repenting and asking Jesus to forgive our sins.
