According to the SAR, the tongue is a muscular organ located in the oral cavity, mobile thanks to 17 striated muscles innervated by the greater hypoglossal..
Brother Santiago describes that the tongue is a very small organ, but when it is not given the proper use, it brings great evils. We are called to watch our words very well, because of every word that comes out of our mouth, we will give account to God.
.
But what does the Bible tell us about the use of the language?.
I. WHEN SAVING OUR LANGUAGE
We keep our soul
Pr 21:23 
We live good days
1Ped 3:10
** II. WHAT DOES THE LANGUAGE DO WHEN IT GIVES YOU MISUSE?**
It produces contentions.
Pr16:28
Take away the best friends
Pr 17:20
Lead to impiety
2Tim 2:16
III. WHAT GOD RECOMMENDS
Do not go gossiping
Lv. 19:16
He abhors a lying tongue.
Pr 6:16-17
IV. SANTIAGO SAYS THAT NO MAN CAN DOMAR HIS LANGUAGE
Death and life are the power of the tongue.
Prov. 18:21
In the many words there is no sin
Prov 10:19 
Finally Our words must be used to love and not to destroy. Christians must be recognized for their love, first with God and then with others. Our words should be used to heal, help, teach, edify and of greater importance to proclaim the good news of Jesus..
Also remember the words of the Apostle Peter: "For whoever wants to love life and see good days, hold back his tongue from evil, and his lips speak no deceit. 1 Pet 3.10. God allow us to use this member for his praise and glory.
Recall the words of the Apostle Paul to the brothers of Philippi
