I heard them say the other day that Azusa Street meetings, when they had it over here in California, that they thought it was a disgrace when they ever entered the song books in the church. They sang in the Spirit. Just as the Spirit gave them utterance, they sang. They danced in the Spirit. They had a great time. And they expected the Word of God in sanctification to separate them from their sins, and they knowed they'd passed from death unto life. What a revival they were having of some forty years ago!
But as Israel did, so did our fathers make a fatal mistake--one thing that's held them in the wilderness another forty years. We find out that instead of being satisfied with what they had, and what God had done for them, and seeing the works of His hands, the fruit of grace providing everything they had need of--even to so much as they didn't have to have a song book. I wish I could've seen that in them days.
