September 23,  the Lord showed me that He had stretched out His hand the second time to recover the remnant of His people,  and that efforts must be redoubled in this gathering time. In the scattering, Israel was smitten and torn, but now in the gathering time God will heal and bind up His people. In the scattering, efforts made to spread the truth had but little effect, accomplished but little or nothing; but in the gathering, when God has set His hand to gather His people, efforts to spread the truth will have their designed effect. All should be united and zealous in the work. I saw that it was wrong for any to refer to the scattering for examples to govern us now in the gathering; for if God should do no more for us now than He did then, Israel would never be gathered. I have seen that the 1843 chart was directed by the hand of the Lord, and that it should not be altered; that the figures were as He wanted them; that His hand was over and hid a mistake in some of the figures, so that none could see it, until His hand was removed. 
Then I saw in relation to the "daily" (Dan. 8:12) that the word "sacrifice" was supplied by man's wisdom, and does not belong to the text, and that the Lord gave the correct view of it to those who gave the
judgment hour cry. When union existed, before 1844, nearly all were united on the correct view of the "daily"; but in the confusion since 1844, other views have been embraced, and darkness and confusion have followed. Time has not been a test since 1844, and it will never again be a test.
The Lord has shown me that the message of the third angel must go, and be proclaimed to the scattered children of the Lord, but it must not be hung on time. I saw that some were getting a false excitement, arising from preaching time; but the third angels message is stronger than time can be. I saw that this message can stand on its own foundation and needs not time to strengthen it; and that it will go in mighty power, and do its work, and will be cut short in righteousness.
Then I was pointed to some who are in the great error of believing that it is their duty to go to Old Jerusalem, [SEE APPENDIX.] and think they have a work to do there before the Lord comes. Such a view is calculated to take the mind and interest from the present work of the Lord, under the message of the third angel; for those who think that they are yet to go to Jerusalem will have their minds there, and their means will be withheld from the cause of present truth to get themselves and others there. I saw that such a mission would accomplish no real good, that it would take a long while to make a very few of the Jews believe even in the first advent of Christ, much more to believe in His second advent. I saw that Satan had greatly deceived some in this thing and that souls all around them in this land could be helped by them and led to keep the commandments of God, but they were leaving them to perish. I also saw that Old Jerusalem never would be built up; and that Satan was doing his utmost to lead the minds of the children of the Lord into these things now, in the gathering time, to keep
them from throwing their whole interest into the present work of the Lord, and to cause them to neglect the necessary preparation for the day of the Lord.
 This applies to the chart used during the 1843 movement, and has special reference to the calculation of the prophetic periods as it appeared on that chart. The next sentence explains that there was an inaccuracy which in the providence of god was suffered to exist. But this does not preclude the publication of a chart subsequently which would correct the mistake, after the 1843 movement was past, and the calculation as then made had served its purpose.
