The tongue carries 9 major sins..

1.  The lying tongue

Lying is one of the things God finds detestable (Proverbs 6:17) and all liars have their place in the lake of fire (Revelation 21:8). You should also note that the devil is the father of liars. 

2.  The Flattering tongue

God hates flattery (Psalm 12:3-4) 

As  believers, we should never praise others because we want to get something from them. 

3.  The proud tongue

A proud/boastful tongue is sinful. Proud believers are full of themselves and learn little from anyone else.

God hates a proud tongue. 

Psalms 12: 3-4 says that God will cut off a proud tongue. 

Humble yourself when God uplifts you.

4. The overused tongue

This is simply talking too much. Ecc 5:3 says that many words mark the speech of a fool, while 

Prov 10: 19 says that the prudent hold their tongues. 

Ecc 5: 2 cautions us against been too quick to speak. We are advised to be persons of fewer words. 

5. The Swift tongue.

This is talking too quick or being too quick to answer without listening. 

Proverbs 18:13 says that to answer without listening is folly and shame. 

James 1:19 tells us to be quick to listen, slow to speak and slow to be angry. 

 6. Back biting tongue.

A sin of the tongue where somebody says good things to your face but says bad and negative things against you when you are not present. 

A backbiter is someone who uses their tongue against you when you are absent. 

 _Prov 25:23_  "The north wind brings forth rain, And a backbiting tongue an angry countenance." 

In _Rom 1:30,_ the scriptures say that those who practice back biting, among other sins, deserve death. 

According to _Prov 6:19_ God hates back biters. 

If you are a believer with this habit, you need to change. If you have ever been a victim of back biting, you need to be still and not back bite back; God will fight for you.

 7. Gossiping tongue

This is the tale-bearing tongue that's forbidden in Psalm 15:3 and Proverbs 18:8. These people engage in conversations about others, usually involving details that are unconfirmed as being true.

Gossip is such a common sin in Churches today. The devil uses believers as altars to harm others. 

God hates a gossiping tongue. Take caution not to spread information against others; you will not only be harming the other person but also injuring your fellowship with God. 

8. The Cursing tongue.

Romans 3:13 "Their throats are open graves; their tongues practice deceit.” “The poison of vipers is on their lips.”  “Their mouths are full of cursing and bitterness.”

God hates cursing tongues and people that curse have no place in the Kingdom. 

In your anger and frustrations, do not utter cursing words against the other person. 

Rom 12:17,18 says that we should not pay evil with evil. We should strive to maintain peace with all men and never seek to revenge; vengeance belongs to the Lord. 

It is not good for people to curse each other after a fall out. Same case applies to parents as far as their children are concerned.

 9. The Piercing tongue

The piercing tongue is sinful as revealed in Proverbs 12:18. While conveying a message to you, these people tend to speak indirectly in reference to something that concerns you.

Do not use your tongue indirectly against someone an effort to mock them. 

God hates a tongue that pierces others. 

James 3: 9 

"With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness."

Jesus entered into a covenant with us at Calvary when he spat the bitter drink; wine mixed with myrrh offered to him. He cleansed and exchanged all the nine sins of the tongue with clean tongues supposed to be used to glorify God. 

How do you use your tongue as a believer? 

 _In which of these areas are you guilty? Make a deliberate and conscious effort to control your tongue lest it leads you to hell. Allow the Holy Spirit to reign over your tongue today!_

A friend of Jesus. 

Be blessed.
