If you answered “the Counselor” or “the Comforter” or “the Spirit of truth” or simply “the Spirit,” you’re correct. All these names refer to the Holy Spirit, sometimes called the Holy Ghost. You may recall from Lesson One that God is really three-in-one—the Father, the Son, and the Holy Spirit. When Jesus (the Son) was on this earth, He promised to never leave us alone. So after returning to heaven, He lived (and continues to live!) on earth through the Holy Spirit. We can’t see the Holy Spirit, but His presence and power are very real.
   One of the symbols used in Scripture for the Holy Spirit is oil (1 Samuel 16:13). To be filled with the Holy Spirit, then, is to have the “oil effect.”
   Let’s discover what the “oil effect” is. What does the Holy Spirit do?
   According to the Bible:
   • The Holy Spirit helped create the world
     (Genesis 1:1, 2).
   • He directed the writing of the Scriptures
     (2 Peter 1:21).
   • He guides us to find the truth about God
     (John 16:13).
   But the most important job of the Holy Spirit is bringing a complete change in our lives.

2. Read John 3:3–5. What did Jesus call this change?
 believing the truth
 being born again
 getting a makeover

   When our lives are filled with the oil of the Holy Spirit, everyone can see the difference! We become a new person with the desire and ability to follow God.
