Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit. You should not be surprised at my saying, ‘You must be born again.’ The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.”
A lot of nonsense is talked about 'spirituality'. It is all about letting go of your body, letting your mind drift and surrendering to the 'forces of the Universe'. It goes with Green issues, Gaia, wind chimes, crystals, Nature, sustainability, vegetarianism, and macrobiotic diets, and it goes against anything to do with reason, logic, planning, chemicals, genetics, science or materials.
Not so with the Holy Spirit. The Spirit is purposeful, thoughtful, concerned and a person. He is there to point people to Jesus. He stands alongside, encouraging, controling, thinking, planning, guarding and protecting. That 'other' spirituality is just about being controled by your emotions.
