What answer to this question can you draw from Revelation 6:11-7:3?
Revelation 6:11 is fulfilled when the fifth seal is broken on the little scroll that Christ has taken from the hand of the Father (Rev. 5:6, 7; Rev. 6:9). The dead are vindicated in the pre-advent judgment (Rev. 6:11). Their living brethren are made "complete," "perfect," in the sense of victorious over sin, during the same pre-advent judgment. Then Christ comes (Rev. 6:12-17). The question asked in verse 17 is answered in Revelation 7:1-8. Those who are able to stand without fear as Jesus comes in the clouds are those who are sealed in their foreheads before the winds of strife are let loose, before the close of probation.
"Reference to our published works will show our belief that the living righteous will receive the seal of God prior to the close of probation." -Selected Messages, bk. 1, p. 66.
"The only hope for any man lies through Jesus Christ.... The pure and holy garments are not prepared to be put on by any one after he has entered the gate of the city, All who enter will have on the robe of Christ's righteousness, and the name of God will be seen in their foreheads. This name is the symbol which the apostle saw in vision, and signifies the yielding of the mind to intelligent and loyal obedience to all of God's commandments."-Sons and Daughters of God, p. 370.
"Just before we entered it [the time of trouble], we all received the seal of the living God. Then I saw the four angels cease to hold the four winds, And I saw famine, pestilence and sword, nation rose against nation, and the whole world was in confusion."-Ellen White Comments, SDA Bible Commentary, vol. 7, p. 968.
What are the spiritual characteristics of living believers when Christ comes? Rev. 14:4, 5; Rev. 15:2-4.
Those who receive the end-time seal of God are the righteous living on the earth when Jesus comes, They stand unafraid as Jesus appears in the heavens (Rev. 6:17; Rev. 7:1-3). They are "redeemed from the earth" (Rev. 14:3, RSV), "from mankind" (verse 4, RSV). "These, having been translated from the earth, from among the living, are counted as 'the first fruits unto God and to the Lamb.' "-The Great Controversy p. 649. (Compare Early Writings, p. 15.)
