The 'vision' here is not personal ambition or an organisation's mission statement — it is prophetic revelation, the Word of God. Where Scripture is not preached, taught, and obeyed, people throw off restraint and society unravels. The second half is the positive answer: the one who keeps the law — who lives by God's Word — finds true happiness. This verse is a call to keep Scripture central in every home and community.
Memory phrase: God's Word gives life.
Talk about it: What happens to people when they stop listening to God's Word?
Prayer: God, help me hear and obey Your Word every day.
