(Proverbs 10:27 KJV) The fear of the LORD prolongeth days: but the years of the wicked shall be shortened.
I can think of many reasons why “fear” (3374) “prolongs” (3253) “days” (life NASB) (3117) [yom].
Fear can keep you from doing something stupid. A fear of heights can keep you away from places that invite falling. Fear can keep you from swimming in dangerous surf. Fear can keep your mouth shut at key times. Those are obvious.
But we are talking about the fear of the “Lord” (3068) [Yahveh]. This is the word that is translated Jehovah four times in the KJV. This is not the craven fear of terror but the holy awe of the eternal God. This is a fear that not only keeps us from evil but transforms our inner being. When you are transformed there are consequences, good ones.
I have read reports that say that people who worship regularly tend to be happier, more successful and, yes, live longer. I didn’t need to read the research, I have already read the Word.
So? You already have what Spock wishes for you. You are going to live long and prosper. And then you will live forever and prosper more.
