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 statues;
I will not forget your word.
Psalm 119:9-16 (ESV)
