Modern versions replace "vision" with "revelation," but the choice is negligible because God's revelation is the true and most important vision (foresight, discernment, insight) for our lives. The Living Bible paraphrases this verse as, "Where there is ignorance of God, the people run wild, but what a wonderful thing it is for a nation to know and keep His laws!" An old English version based on the Latin Vulgate provides a fascinating rendering in light of what has happened recently in the church: "When prophecy shall fail, the people shall be scattered." Adam Clarke comments, "Where divine revelation, and the faithful preaching of the sacred testimonies, are neither reverenced nor attended, the ruin of that land [or church] is at no great distance."
All these renderings show a measure of cause and effect. The vision a person has is the cause, and the effect is the way he then conducts his life. Where there is a true vision, or revelation of God, it motivates those who have reverence for it to conduct their lives in a way that produces good fruit - happiness. If the vision that guides is not from God, the people are motivated to "run wild" or "cast off restraint." That is, they will not discipline themselves to take proper responsibility, and the result is they perish - quite a contrast to the satisfying result of keeping God's laws!
There can be no doubt about what vision produces. It enhances our perception of what will occur or be produced if a certain course is followed. Thus, it increases our discernment and sharpens our judgment about which way we should go. If the vision, the foreseen result, seems good to a person, he is motivated to proceed in that direction. When vision and the fear of God combine, they produce a strong stimulus to obey Him. Vision gives a mental picture of results, and the deep and abiding respect for God produces a compelling inclination to please Him.
