But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming.—1 Corinthians 15:23 JNN 236.1
In the summer of 1844, midway between the time when it had been first thought that the 2300 days would end, and the autumn of the same year, to which it was afterward found that they extended, the message was proclaimed in the very words of Scripture: “Behold, the Bridegroom cometh!” JNN 236.2
That which led to this movement was the discovery that the decree of Artaxerxes for the restoration of Jerusalem, which formed the starting point for the period of the 2300 days, went into effect in the autumn of the year 457 B.C., and not at the beginning of the year, as had been formerly believed. Reckoning from the autumn of 457, the 2300 years terminate in the autumn of 1844.... JNN 236.3
The slaying of the Passover lamb was a shadow of the death of Christ. Says Paul: “Christ our Passover is sacrificed for us” (1 Corinthians 5:7). The sheaf of first fruits, which at the time of the Passover was waved before the Lord, was typical of the resurrection of Christ. Paul says, in speaking of the resurrection of the Lord and of all His people: “Christ the first fruits; afterward they that are Christ’s at His coming” (1 Corinthians 15:23). Like the wave sheaf, which was the first ripe grain gathered before the harvest, Christ is the first fruits of that immortal harvest of redeemed ones that at the future resurrection shall be gathered into the garner of God. JNN 236.4
These types were fulfilled, not only as to the event, but as to the time. On the fourteenth day of the first Jewish month, the very day and month on which for fifteen long centuries the Passover lamb had been slain, Christ, having eaten the Passover with His disciples, instituted that feast which was to commemorate His own death as “the Lamb of God, which taketh away the sin of the world.” That same night He was taken by wicked hands to be crucified and slain. And as the antitype of the wave sheaf our Lord was raised from the dead on the third day, “the first fruits of them that slept.”—The Great Controversy, 398, 399. JNN 236.5
Further Reflection: When studying prophecy, how can I avoid being “sincerely wrong,” as were Adventist pioneers who mistakenly believed Jesus would return on October 22, 1844? JNN 236.6
