John 14:16-17 “And I will ask the Father, and he will give you another Counselor to be with you forever–the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.”

The very fact that we believe in Jesus is evidence that he has kept this promise. “No one can say, ‘Jesus is Lord,’ except by the Holy Spirit,” Paul later wrote to the Corinthians. We have the Spirit, and we believe in Jesus, but that is the one thing the world cannot do.

Jesus doesn’t want us to be surprised that the whole world doesn’t embrace our Savior and his teachings. It neither accepts, nor knows, nor sees the Spirit who would make that possible. Remember how the Pharaoh of Egypt reacted when Moses brought the miraculous plagues? When his own sorcerers were not able to imitate some of them, they told the Pharaoh, “This is the hand of God.” But he would not see the power of God working right in front of his nose.

Remember how the Pharisees reacted to Jesus during his ministry? They heard the same good teaching that everyone else heard. They saw his many miracles. They had to admit that some of them were no trick, and nothing a mere man could do, like healing a man born blind or raising Lazarus to life four days after he died. But they would not hear and they would not see what everyone else did. It was all so clear, so undeniable, that Jesus warned them that they were toying with sinning against the Holy Spirit, who was tugging at their hearts through Jesus’ ministry.

Sometimes I hear Christians today speak as though they are befuddled by the world in which we live. How is it possible for people to reject common decency in so many areas of life? Why do more and more people abandon Biblical beliefs accepted by nearly everyone for thousands of years? How do some people believe such outlandish things about Jesus, rejecting his virgin birth, or claiming he was sinful, or denying his body came back to life and left his tomb? Remember, they lack the Holy Spirit. “The world cannot accept him, because it neither sees him nor knows him.”

But you do. “But you know him, for he lives with you and will be in you.” The Holy Spirit lives with us. We are exposed to him constantly. He inhabits the room whenever we are gathered around God’s word and sacraments. He lives in our Bible studies, the Christian books and magazines we read, the Christian music we listen to. He has set up shop in our hearts. They may be dilapidated old fixer-uppers that should have been condemned by the building inspectors long ago, but the Holy Spirit has moved in anyway. He went right to work setting things straight in there. He opens the Scriptures to us, if not so that we can fully understand them, then at least so that we can accept that what they say is true and is God speaking to us. He maintains our faith.

The Spirit continues to do for us the kinds of things Jesus was doing for his disciples when he was with them, which is why it is good that we have him with us while Jesus is away.
