Illusory Follies

How can a young man keep his way pure?
  By guarding it according to your word.
With my whole heart I seek you;
  let me not wander from your commandments!
I have stored up your word in my heart,
  that I might not sin against you.
Blessed are you, O Lord;
  teach me your statutes!
With my lips I declare
  all the rules of your mouth.
In the way of your testimonies I delight
  as much as in all riches.
I will meditate on your precepts
  and fix my eyes on your ways.
I will delight in your statutes;
  I will not forget your word.
