“My hair has never been cut,” he confessed, “for I was dedicated to God as a Nazirite from birth. If my head were shaved, my strength would leave me, and I would become as weak as anyone else.” Judges 16:17

Do not love this world nor the things it offers you, for when you love the world, you do not have the love of the Father in you. For the world offers only a craving for physical pleasure, a craving for everything we see, and pride in our achievements and possessions. These are not from the Father, but are from this world. And this world is fading away, along with everything that people crave. But anyone who does what pleases God will live forever. 
1 John 2: 15 – 17
