He is the Spirit of truth. The world is unable to receive him because it doesn’t see him or know him. But you do know him, because he remains with you and will be in you. John 14:17.

“But you have received the Holy Spirit, and he lives within you, so you don’t need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what he teaches is true, it is not a lie. So, just as he has taught you, remain in fellowship with Christ.” READ YOUR BIBLE EVERY DAY.
