V. 10. "In the spirit." We cannot describe this psychological state other than to suppose that all the channels of his being were open toward God, ready for the reception of any divine communication. Had he not been "in the spirit," but spending the holy day after the modern fashion, it is needless to say no voice or vision would have come to him. The man who is in the spirit on the Lord's day is the one who hears God speak and gets his message. "The Lord's day," — evidently the Christian Sabbath or the first day of the week, indicating what day the apostles observed.
