How can we know what is “good” (2896a) and what is bad? First we need to acknowledge that good and bad exist. Then we need to “perceiveth” (senses NASB) (2938). Perception is something that we can develop. The word literally means to taste and is used that way most times in the OT. One place that is not so literal is the one you are most familiar with:
(Psalms 34:8 KJV) O taste and see that the LORD is good: blessed is the man that trusteth in him.We need to develop the ability to discern between the bad, the good, the better and the best. Sometimes this can only be done through experience. I have been drinking coffee for years. I am no connoisseur, but I am getting to the place where a taste will tell me if it is good or not. At first, when I drank it to stay awake, I doctored it with loads of sugar and cream. Now I can enjoy it black.
Some things such as liver and menudo I don’t need to taste physically. The smell is enough to tell me, “Don’t go there.” Some parts of life we need to taste to see what is needed, like a cook preparing a special recipe with vague amounts of spices. It becomes seasoned to taste. Sometimes we can get the advice of others as in your first visit to a restaurant and asking, “What is really good here?”
And of course the one you know I am aiming for: Know the Word. It gives me a standard to measure by. I can rely on nothings else.
So? Each of us is responsible for our choices. Make them informed. Understand that the best source of information is the Bible. Read, taste, perceive.
