The truth and benefit of this verse can only be proved true for a person who strives to live it out. Wisdom is only proven if the person possessing it applies his knowledge to daily living.
As we live in a broken world, temptation and evil abounds, so it’s actually challenging to live consistently with wisdom.
But I believe that as we continue to pursue wisdom, despite having many failures, we eventually gain knowledge and understanding of the best pathways in life, which will ultimately help us to be happy and content in whatever circumstances.
The way we respond to everything that happens to us, good or bad, makes us the person that we are.
