The LORD said: Ezekiel, now say to the wind, “The LORD God commands you to blow from every direction and to breathe life into these dead bodies, so they can live again.”
But I tell you that I am going to do what is best for you. That is why I am going away. The Holy Spirit cannot come to help you until I leave. But after I am gone, I will send the Spirit to you.
Jesus was talking about the Holy Spirit, who would be given to everyone that had faith in him. The Spirit had not yet been given to anyone, since Jesus had not yet been given his full glory.
