“O Timothy!  Guard what was committed to your trust, avoiding the profane and vain babblings and contradictions of what is falsely called knowledge--by professing it, some have strayed concerning the faith…”  
1 Timothy 6:21-22
  
Here Paul is closing his first letter to Timothy and it is the fifth charge he is making to the young pastor.  For Believers, also, is the charge to avoid vain babblings (empty chatter) and contradictions that the world wrongly call knowledge--we have a great amount of that today!  
 
Scripture has much to say about our talk, words, and about our mouth, tongue and lips. I will only mention a few verses here (Do a further study).
 
“But shun profane and vain babblings, for they will increase to more ungodliness.  And their message will spread like cancer…”  
2 Timothy 2:16-17
 
“Keep your tongue from evil,
And your lips from speaking guile.”  Psalm 34:13
 
In Proverbs we see:
“In the multitude of words sin is not lacking,
But he who restrains his lips is wise.”  Proverbs 10:19
 
“In all labor there is profit,
But idle chatter leads only to poverty.”  Proverbs 14:23
 
“A fool vents all his feelings,
But a wise man holds them back.”  Proverbs 29:11
 
Ephesians 4:30-31,
“And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.  Let all bitterness, wrath, anger, clamor (loud quarreling), and evil speaking be put away from you with all malice.”
 
James has much to say about the tongue (Read James 3:1-10),
“With it we bless our God and Father, and with it we curse men, who have been  made in the likeness of God.  Out of the same mouth proceed blessing and cursing.  My brethren, these things ought not to be so.”
 
We need to heed what King David asked and do the same!
“Set a guard, O LORD, over my mouth;
Keep watch over the door of my lips.”  Psalm 141:3
 
Concerning false doctrine:
“Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ.”  
Colossians 2:8
 
“Do not be carried about with various and strange doctrines.  For it is good that the heart be established by grace, not with foods which have not profited those who have been occupied with them.”  
Hebrews 13:9
 
“Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world.”  
1 John 4:1
 
Jesus speaks to his disciples,
“And Jesus answered and said to them: ‘Take heed that no one deceives you.  For many will come in My name, saying “I am the Christ,” and will deceived many.’”  
Matthew 24:4-5 
 
Jude tells us in verse 4,
“For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into licentiousness and deny the only Lord God and our Lord Jesus Christ.”  
 
Paul to Timothy,
“Now as Jannes and Jambres resisted Moses, so do these also resist the truth: men of corrupt minds, disapproved concerning the faith; but they will progress no further, for their folly will be manifest to all…”  
2 Timothy 3:8-9
 
“Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned. And avoid them.  For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple.”  Romans 16:17-18.
 
This time we live in is filled with deception of all kinds!  We have been warned!  Let us heed what Scripture tells us for it has been made very clear in 1 Timothy 3:16-17,
“All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man (women, too) of God may be complete, thoroughly equipped for every good work.”
 
Thank you Lord for your word and the Holy Spirit who opens it up to us.  How grateful we are!  Amen
