Proverbs 4 shows us that wisdom and understanding are the key treasures of life: “wisdom is supreme, therefore get wisdom. Though it cost all you have, get understanding.” (Prov 4:7)
This theme is continued in the metaphor of a path or journey. I like the way the Message personifies these ideas: ”I’m writing with clear directions to Wisdom Way; I’m drawing a map to Righteous Road. I don’t want you ending up in blind alleys or wasting time making wrong turns… Don’t take Wicked Bypass; don’t so much as set a foot on that road.” (Prov 4:10-13)
As Jesus taught in Matthew 7, there are basically only two paths in life: the broad path that leads to destruction and the narrow path which leads to life. ” The ways of right-living people glow with light. But the road of wrongdoing gets darker and darker – travellers can’t see a thing; they fall on their faces.” (Prov 4:18-19)
It doesn’t always look like that. The world is full of bright lights, making cities and towns shine even at night, whilst the narrow paths of the countryside can often seem shrouded in gloom. 
But God’s Word is a lamp to our feet, a light to our paths (Ps 119:105). 
We find that there is light for the journey: our job is to ‘watch our step’, neither looking to the right or left (Prov 4:26-27), but fixing our eyes on Jesus (Heb 12:2)
