⁹ How can a young person stay on the path of purity?
    By living according to your word.
¹⁰ I seek you with all my heart;
    do not let me stray from your commands.
¹¹ I have hidden your word in my heart
    that I might not sin against you.
¹² Praise be to you, Lord;
    teach me your decrees.
¹³ With my lips I recount
    all the laws that come from your mouth.
¹⁴ I rejoice in following your statutes
    as one rejoices in great riches.
¹⁵ I meditate on your precepts
    and consider your ways.
¹⁶ I delight in your decrees;
    I will not neglect your word. Psalm 119:9-16

What is the path of purity?

Aleph
1 Blessed are those whose ways are blameless,
who walk according to the law of the Lord.
2 Blessed are those who keep his statutes
and seek him with all their heart—
3 they do no wrong
but follow his ways.
4 You have laid down precepts
that are to be fully obeyed.
5 Oh, that my ways were steadfast
in obeying your decrees!
6 Then I would not be put to shame
when I consider all your commands.
7 I will praise you with an upright heart
as I learn your righteous laws.
8 I will obey your decrees;
do not utterly forsake me. Psalm 119

What is the difference between steadfastness and perfection?
