What comes out of the Mouth comes from the Heart

What comes out of the Mouth comes from the Heart      

Matthew 12:34-37 (KJV) 
34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaks.    
 
35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.    
 
36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. 37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.    
 
Matthew 15:10-11, 16-20 (KJV) 
10 And he called the multitude, and said unto them, Hear, and understand: 11 Not that which goes into the mouth defiles a man; but that which cometh out of the mouth, this defiles a man.  
 
16 And Jesus said, Are ye also yet without understanding? 17 Do not ye yet understand, that whatsoever enters in at the mouth goes into the belly, and is cast out into the draught?  
 
18 But those things which proceed out of the mouth come forth from the heart; and they defile the man.  
 
19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:  
 
20 These are the things which defile a man: but to eat with unwashed hands defiles not a man.  
 
1 Corinthians 3:16-17 (KJV) 
16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?  
 
17 If any man defiles the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.  
 
1 Corinthians 6:18-20 (KJV) 
18 Flee fornication. Every sin that a man does is without the body; but he that committed fornication sinned against his own body.  
 
19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.  
 
1 Timothy 1:5-11 (KJV) 
5 Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned:6 From which some having swerved have turned aside unto vain jangling; 7 Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.  
 
8 But we know that the law is good, if a man use it lawfully; 9 Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, 10 For whoremongers, for them that defile themselves with mankind, for men stealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;
 
11 According to the glorious gospel of the blessed God, which was committed to my trust.
