2 Timothy: Flee also youthful lusts, but pursue righteousness, faith, love, peace

20 But in a great house there are not only vessels of gold and silver, but also of wood and clay, some for honor and some for dishonor. 21 Therefore if anyone cleanses himself from the latter, he will be a vessel for honor, sanctified and useful for the Master, prepared for every good work.

22 Flee also youthful lusts; but pursue righteousness, faith, love, peace with those who call on the Lord out of a pure heart.

Youthful Lust is one of the biggest battle in life for men.
