John 14:15-18

Jesus said to his disciples: If you love me, you will do as I command. Then I will ask the Father to send you the Holy Spirit who will help you and always be with you. The Spirit will show you what is true. The people of this world cannot accept the Spirit, because they don't see or know him. But you know the Spirit, who is with you and will keep on living in you. I won't leave you like orphans. I will come back to you.
