There is perhaps no man on this planet who does only good things without committing any sin. It is human nature, we all err.
And the tongue is most of the time the culprit.
Although a horse has great strength, it has no understanding; so it must be harnessed with bits and bridle to make him obey according to the will of the rider.
Similarly, the tongue is a small part of human body, but its power and influence for good or bad is amazingly greater than its size. It is like a small lighted match stick which lights big fires.
Every kind of beasts, birds or creature of the sea and earth has been tamed by mankind, but no man can tame the false, deceitful and perverse tongue that works like the piercing of the sword.
It is unruly evil, full of deadly poison. At one end, the tongue blesses the Lord God, and at the other end it curses man who has been made in the image of God. From the same mouth comes blessings as well as curses.
So the tongue should be tamed. We should teach our children to speak gracious words from the very beginning. We must realise harsh and nasty remarks result in problems and create differences and fights.
One must seek to be at peace with others, preferring them to yourself. Discard any attitude or practice that hinders the tongue for speaking kind, merciful and polite words. It is only through a sustained daily effort that one can apply elegant words in life.
The Bible says, " Pleasant words are like a honey comb, sweetness to the soul and health to the bones."
So be careful in what you say, measure every word. Do not speak unless it is necessary.
The person who is humble and slow in anger is better than the mighty man of anger.
One who speaks politely and sweetly is loved and appreciated by everybody. Don't you want to be such a person?
