Based on the available Ellen White book sources, there is no direct statement that a "great multitude" (in the sense of a vast number of living people) will be alive when Jesus comes. Instead, the writings consistently describe:
- The 144,000 as a special group who are alive and translated without seeing death at Christ’s coming.
- The righteous dead are resurrected at the second coming, and together with the living saints (the 144,000), they are "caught up together... to meet the Lord in the air" (see Early Writings, p. 16; 1 Thessalonians 4:16-17 referenced in Ellen White's writings).
- The wicked are destroyed by the brightness of Christ’s coming.
Ellen White does refer to a "great multitude" in the context of Revelation 7, but in her writings, this group is not specifically identified as those alive at Christ’s return. The focus is on the 144,000 as the living saints at the time of Jesus’ coming, joined by the resurrected righteous.
For example:
> "The 144,000 shouted, Hallelujah! as they recognized their friends who had been torn from them by death, and in the same moment we were changed and caught up together with them to meet the Lord in the air." (Early Writings, p. 16)
> "He will come to raise the dead, and to change the living saints from glory to glory." (The Story of Jesus, p. 177)
Therefore, according to Ellen White’s book sources, the living saints at Christ’s coming are described as the 144,000, and they are joined by the resurrected righteous. There is no explicit statement that a "great multitude" of living people, beyond the 144,000, will be alive at that time.
