(Proverbs 3:18 KJV) She is a tree of life to them that lay hold upon her: and happy is every one that retaineth her.
Notice that there are two verbs that are vital to know wisdom and have it effect your life. First it says we must “take hold” (2388). Then it says we are to “hold fast” (8551). If you come from the Reformed tradition you would tend to think that the second condition is optional. Since I am Wesleyan I tend to think that both are foundational. The world is full of people who will acknowledge that the moral law of the Bible is a good place to start. They tend to go at it cafeteria style. I believe that the Bible is to be taken in its entirety. That means we also have a duty to retain wisdom, as the KJV tells us.
So? Get started if you are still dithering. Once you start don’t stop until you reach what Paul would call the mature man. Wisdom is waiting.
