A teacher is a person who has a wide range of knowledge that can be impacted to others without depletion. He/ she should be well equipped not to mislead their disciple who will follow nothing else but their teaching. However, James warns us of the dangers that comes for teachers in judgment, therefore asking us not to do it without authority. James 3:1Not many of you should presume to be teachers, my brothers, because you know that we who teach will be judged more strictly.(NIV)
He further gets into the imperfect man, who stumble, but also commends any who has kept check on his whole body. Can’t a man keep check his whole body?
In most cases the little things/ parts are the biggest threats in every kind of living. Same case, minute things can bring a change to situations or challenges that face us and otherwise they can change peace into horror.
A disobedient horse can be disciplined by having a bit into its mouth. By these one gains control of the whole horse. Or a ship which is so large and can only be driven by strong winds, it is steered by a very small rudder whenever the pilot wants to go.
