20 And he said, That which cometh out of the man, that defileth the man.
21 For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,
22 Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness:
23 All these evil things come from within, and defile the man.
Mark 7:20-23 KJV
What comes out of the mouth
In Mark 7, Jesus is addressing His disciples privately and telling them that nothing that enters a man can make him unhallowed or unclean. It is what comes out of that man's heart that makes him unhallowed or unclean. He gives us a list of what those things are.
Evil thoughts - This word means inward reasoning, questioning about what is true, doubting, or meditating on evil actions.
Adultery - This is committed when either spouse in a marriage lusts after another person outside of their marriage or a person divorces and remarries while their spouse is living. (Matthew 5:31-32/ Matthew 19:9-12/ Mark 10:11-12/ Luke 16:18/ Romans 7:2-3)
Fornication - This is when a single person not bound by a spouse lusts in their heart or has pre-marital sex. This can also mean prostitution.
Murder - Murder or to kill
Theft - Stealing
Covetousness - Greedy desire to have more, avarice
Wickedness - Malice, evil purposes and desires
Deceit - craft, guile, trick, probably meaning to decoy
Lasciviousness - unbridled lust, excess, outrageousness, shamelessness
Evil eye - can mean jealous or evil mind
Blasphemy - Slander, speech injurious to another's good name, impious
Pride - Haughtiness, arrogance, the character of one who, with a swollen estimate of his own powers or merits, looks down on others and even treats them with insolence and contempt.
Foolishness - thoughtlessness, recklessness, senseless, folly
Jesus says that all of these come from within a person's heart. Daily, we must DENY ourselves and resist the temptation to sin. We can be free from these if we submit to the Holy Spirit and not walk in the flesh.
We have a choice, choose wisely!
