I spend hours and hours reading and meditating and wrestling with the text. 
 What I wrestle is that I must be prepared to obey what I see in the word because I can never hope to lead others beyond what I have practiced.
 The great Scottish Reformer John Knox was so awed and burdened by the responsibility to declare God's Word faithfully that, before his first sermon, he wept uncontrollably and had to be escorted from the pulpit until he could compose himself. 
 It is an honor with humility to teach 
 However, to be a great teacher it does not require eloquent in speech but rather integrity in his speech.  
 We see Apostle Paul who confessed that he lack eloquence in his speech.
We have Moses who was heavy or slow of speech.
 
The account given in the Talmud (The Jewish Scribes claim the Talmud is partly a collection of traditions Moses gave them in oral form) is as follows: Pharaoh was one day sitting on his throne with Moses on his lap, when the child took off the king's crown and put it on his own head. The "wise man"tired to persuade the king that this was treason, for which the child ought to be put to death; but Jethro, priest of Midian, replied, "It coals, and you will readily see he will prefer the red-hot coals." The experiment being tried, the little boy snatched up the live coal, put it into his mouth, and burnt his tongue so severely that he was ever after "heavy or slow of speech"

Because it is not how we say it, rather it is what we say and how we live it.
 
Teachers are held to a higher standard in what they say, for the obvious reason that what they say exerts a powerful spiritual influence on others. Teachers are in special danger of misusing their tongues and thereby incurring stricter judgment by God.
 
James 3:1 (NIV)
Not many of you should presume to be teachers, my brothers, because you know that we who teach will be judged more strictly. 
 The Greek noun krima ( judgment ) in the New Testament it is most often used as a warning,. For unbelievers, the future tense (will incur) refers to the Great judgment spoken of by John in ?Revelation 20:1115?. Believers, on the other hand, will incur ? in the form of chastening in this life.
 It is speaking of greater brokenness for the teachers. 
 James 3:2 (NIV)
2 We all stumble in many ways. If anyone is never at fault in what he says, he is a perfect man, able to keep his whole body in check. 
 Now he goes from specify to general.  Now, he is speaking to all believers. 
 The tongue has extraordinary power to control, even to the extent that if anyone does not stumble in what he says, he is a perfect man. 
 The idea of a perfect man 
 A mark of true spiritual maturity is that of a man who can control what he/she says.
 To control speech is in itself an act of faith. 
 If one can control the tongue, then one can control the body. Just as there should be no separation between faith and works, so also there should be no separation between speech and life.
 Because words usually lead to actions. 
 
Why is tongue so powerful? James teaches us in the following verses
James uses strong images to show us
1.      The power to direct (like bits and rudders), 
2.      The power to destroy (like fire and wild animals)
3.      The power to delight (like flowing springs and fruit trees).
The tongue has power to direct (3:3-5a).
 
James 3:3-5 (NIV)
3 When we put bits into the mouths of horses to make them obey us, we can turn the whole animal. 4 Or take ships as an example. Although they are so large and are driven by strong winds, they are steered by a very small rudder wherever the pilot wants to go. 5 Likewise the tongue is a small part of the body, but it makes great boasts.
 
Both the bit and the rudder must overcome contrary forces.
