Morning, this is a good question from you and I like it.

wisdom, knowledge and understanding, I will say the three are so important, because we need the three in our life.

If you have knowledge of something without understanding it, the knowledge is a wastes, some people do not apply the knowledge well, because they don't understand it.

For example a student have knowledge of math, but he didn't understand it, he will need someone who understands better than him to explain to him.

Wisdom is a greatest among the three, whatever you are doing, you need apply wisdom in life, some do Wise truly, but if you don't have knowledge and understanding.
The wisdom is also a wastes.

Examples a husband and wife, one can be wise and don't understand the husband or wife and in marriage you must understand your spouse, you must have the knowledge of how to deal with your spouse, so that there won't be fight.

And you must apply wisdom in everything you do.

To me the three is very important, Even in the bible solomon ask God for the three, wisdom, knowledge and understanding.

And in the book of proverbs all through the did not choose one out of the three, he use the three word.

Because he knows we need the three, if you have one or two out of the three, you still need someone to that will help you with the third one.
