If only we know how far words go, we will mind every word that comes out of our mouth. If only we know either the damage or the good it does we will take much caution. Our words can go as far as making someone either give this life to CHRIST or not.
I usually say this if GOD honours His words more than His name, we children of HIS shouldn't take likely our words that proceeed out of your mouth.
James trying to bring full understabding that good water and bad water cannot flow from the source. A bad tree produces a bad fruit. Our words are seeds planted and is generated into a fruit; and it is either for good or for bad.
Many people do not know the implication of the negative words they say. We shall be either condemned or justified by the words of our mouth. Good words encourage, bad words discourages. You see many people are so eager just to hear the opinion of someone they really respect or value.
They do so because they words of the person has an effect on him and of course it has to be a positive effect. We should try as much as possible to be conscious of what we say and where we say then. Sometimes where we say certain things can affect our reputation. Some people wait to trap you with your words and use them against you.
That is why the Scribes, the Pharisees, the teachers of the law constantly kept questioning Jesus, waiting to trap Him with whatever He says. They knew they could manipulate Him with His words. Jesus knew this and He was always careful of that.
Not only because He didn't want to be found guilty before then but also because it was His lifestyle, He had learnt that His words are powerful. Watching what comes out of His mouth, became His commitment, lifestyle. His words encouraged people and they usually found nothing to use against Him.
I know it can be very tempting to respond to some certain comments made, but see Jesus as an example to all. You gain honour and respect when you keep silence over things that should normally hurt you.
Matthew 27:14.
And he answered him to never a word; insomuch that the governor marvelled greatly.
The governor marvelled at Jesus discipline not to be angry at criticisms. As Christians what we say matter a lot. People watch us, Jesus watches us. No circumstance is an excuse for you to use words that do not glorify GOD.
Honour GOD in your mortal bodies, with everything and He shall give you grace to say words that are seasoned with salt.
