The absolute worst thing that a person can do, is state an opinion, or make a comment, that is inaccurate, because of the lack of correct understanding, and therefore when others see or hear or read it, might cause concern or doubt or misunderstanding, which will lead them to wrong or delayed conclusions regarding Christianity and truth.
Is far better to remain silent, and keep your opinions to yourself, than to blurt out statements that can inadvertently bring harm to others.
The Bible says, be silent in church, and that applies to everyone.
There is only one instructor in a classroom, not two instructors.
There is only one chef in the kitchen, not two chefs.
And so it goes in life.
To be a student or to be a subordinate in any situation, and to presume authority without a right to that authority, does nothing but cause harm and disruption. And that always leads to harm for others, who might not have a clear picture of what is going on.
Later verses in this Psalm, will indicate deep perplexing doubts as to divine administration.
All too often, life is not clear. And all too often, life is not fair. And the how’s and why’s of it all can cause discouragement and anxiety and questioning as to why.
With a consistent and regular daily study, all questions are eventually answered. But until they are answered, a person needs to learn self-discipline and patience, and certainly the self-control of one’s own mouth.
Complaining is a part of life, and frustration almost always produces complaining.
But as David states in this Psalm, that he will heed his own ways. Meaning he will examine his own ways and exercise self-control, so as not to bring, or perpetuate doubt or misunderstanding, or even sins, in others, as a result of his own ill thought out comments.
So, we are to keep our tongue in check, and our mouth muzzled, so long as there is anyone within hearing distance, or reading distance, that might mistake our words, or our tone, as a negative with regard to Christianity.
