The heart of him that hath understanding seeketh knowledge: but the mouth of fools feedeth on foolishness.
Life is full of decisions that must be made, and for every decision there are either positive or negative consequences. In order to make the best decisions possible we need to have the best advice and wisdom we can to help us make the right decisions at the right time. The vast majority of the time people listen to poor advice from their fellow men, people that claim to be experts, professionals, or gurus, but who are ultimately just blind, deaf, and dumb, whose advice will only cause harm to those that would be foolish enough to follow it.
If you want to be wise and succeed in this life you must take counsel from God, the only true and wise counselor. If you feed yourself on a steady diet of wisdom you will make wise decisions and enjoy the fruits thereof, if you feed yourself on a diet of foolishness and lies you will make foolish decisions and will suffer the consequences thereof.
What are you feeding on? The wisdom of God or foolishness of men?
