Responding to the call to become footstep followers of Jesus is voluntary. Not all are called, and only a relative few answer this call. “Many are called, but few are chosen.” (Matthew 22:14) As has been shown in the Tabernacle arrangement, the purpose of the call of a few now—the priesthood class—is for the blessing of all in the future. The role of this heavenly class is to bring all into atonement (at-one-ment) with God.
Again, it is important to understand this point—the nation of Israel surrounding the Tabernacle, represents the world of mankind—those outside of fellowship with God. They do not see the sacrifice of Christ, yet the purpose of the Tabernacle sacrifices was to bless all the people.
When the call of the Church, the footstep followers of Jesus, has finished its work—and the sacrificing of this symbolic priesthood is all finished—only then will the blessing of all the families of the earth take place. Then the promise originally given to Abraham will be fulfilled: “In thee and in thy seed shall all the nations of the earth be blessed.” Genesis 22:18
The fulfilling of this grand promise has been made possible by the sacrifice of Jesus, who “…tasted death for every man. (Hebrews 2:9) “Who gave himself a ransom for all to be testified in due time.” (1 Timothy 2:6) This is truly “good tidings of great joy, which shall be to all people.” Luke 2:10
As God covered the type and hid its beauty under curtains and rough, unsightly skins, so the glories and beauties of spiritual things are seen only by those who enter the consecrated condition—the Royal Priesthood. These enter a hidden but glorious state which the outside world fails to see or appreciate. Their glorious hopes and also their standing as New Creatures are hidden from their fellow men. Their activities seem incomprehensible to those without.

Soon, however, the amazing illustration of the blessing of those in darkness will begin to take place. As in the type, so in the reality, all the people will learn to appreciate the sacrifices made on their behalf. At that time, whosoever will, may obey and live forever in happiness and communion with their loving Creator. Isaiah 26:9; Revelation 22:17
“And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the Tabernacle of God is with men, and He will dwell with them, and they shall be His people, and God Himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.” Revelation 21:2-4
