Your Word is a lamp unto my feet

 "Your word is a lamp to my feet and a light to my path." (Psalm 119:105 ESV)

No matter how well I think I know my way around the house in the dark, every once in a while I will bump into something. That's why I need to turn on the light when I enter a room because I don't like bumping into things. It hurts.
In the longest chapter in the Bible, Psalm 119, King David for 176 verses talks about how much he loves God's Word. In fact, you can't possibly understand any of that great chapter until you come to the grips that King David is talking about the authority, usefulness, value and truthworthiness of Holy Scripture.
Just check this out:
⁵ Oh that my ways may be steadfast
    in keeping your statutes!
⁹ How can a young man keep his way pure?
    By guarding it according to your word.
²⁴ Your testimonies are my delight;
    they are my counselors.
⁴⁴ I will keep your law continually,
    forever and ever,
⁹⁷ Oh how I love your law!
    It is my meditation all the day.
⁹⁸ Your commandment makes me wiser than my enemies,
    for it is ever with me.
And that was a random sample. It goes on through verse 176 when he writes ¹⁷⁶ I have gone astray like a lost sheep; seek your servant,
    for I do not forget your commandments.

So let's see, King David, a man after God's own heart, writes 176 verses on how important God's Word is. So that should tell us something right there. Usually when I see a person, even a Christian, who's life is shipped wrecked by sin, it nornmally doesn't take too long to figure out had the person just followed God's Word, chances are their life would have been a whole lot easier. That's not to say that following God's Word places our path on a bed of roses. Actually quite the opposite.
The Christian life is one of hardships. What the Word of God does is help us through it and sometimes keeps us from making a bad situation even worst.
