"Joseph asked, "which of all the sects was right that I might know which to join." It was Jesus Christ who answered, telling Joseph not to join any of them. The Lord explained that the churches of the day believed "in incorrect doctrines and that none of them was acknowledged of God as His Church and kingdom" (Teachings of Presidents of the Church: Joseph Smith , 28; Times and Seasons, Mar. 1, 1842, p. 706-707; see also Joseph Smith-History 1:18-19).
From the LDS church website regarding this "First Vision":
"The first vision marked the beginning of the Restoration of the gospel of Jesus Christ in this last dispensation. Joseph Smith was chosen to be the Lord's prophet in the latter days. Over time, the Lord restored His authority and Church through Joseph Smith. God's children were again blessed with revelation through prophets called of God, just as they were in biblical times. Revelation continues to this day through each of God's chosen prophets who have succeeded Joseph Smith."
How is it explained that from the time of Jesus Christ Resurrection ~2,000 years ago billions of people have been saved even to this day without the Church having to be restored?
