It is essential to understand these things. Why? Because what's been revealed to us we're required to know. The secret things that haven't been revealed they're not for us to understand. But it is very clear. These issues are very clear and these are the very issues that we're involved in in this prophetic time period in history. Selected Messages, Book 1, page 192. I have no specific time of which to speak when the outpouring of the Holy Spirit will take place, when the mighty angel will come down from heaven and unite with the third angel in closing up the work for this world. My message is that our only safety is being ready for the heavenly refreshing. Having our lamps trimmed and burning, Christ has told us to watch, for in such as such an hour as you think not, the Son of Man cometh. Watch and pray is the charge that is given us by our Redeemer. Day by day we are to seek the enlightenment of the Holy Spirit, of the Spirit of God, that it may be, that it may do its office work upon the soul and character. Oh, how much time has been wasted through giving attention to trifling things. Repent and be converted that your sins may be blotted out when the times of refreshing shall come from the presence of the Lord.
