We are not to know the definite time either for the outpouring of the Holy Spirit or for the coming of Christ.... Why has not God given us this knowledge?—Because we would not make a right use of it if He did. A condition of things would result from this knowledge among our people that would greatly retard the work of God in preparing a people to stand in the great day that is to come. We are not to live upon time excitement.... (LDE 33.1) 2 I MC VC

You will not be able to say that He will come in one, two, or five years, neither are you to put off His coming by stating that it may not be for ten or twenty years.—The Review and Herald, March 22, 1892. (LDE 33.2) MC VC

We are nearing the great day of God. The signs are fulfilling. And yet we have no message to tell us of the day and hour of Christ’s appearing. The Lord has wisely concealed this from us that we may always be in a state of expectancy and preparation for the second appearing of our Lord Jesus Christ in the clouds of heaven.—Letter 28, 1897. (LDE 33.3) 2 I MC VC

The exact time of the second coming of the Son of man is God’s mystery.—The Desire of Ages, 633 (1898). (LDE 33.4) MC VC
