The Church Is Built upon the Foundation of Apostles and Prophets, and Jesus Christ Is the Chief Corner Stone
19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit.
Elder Jeffrey R. Holland said:
“The apostolic and prophetic foundation of the Church was to bless in all times, but especially in times of adversity or danger, times when we might feel like children, confused or disoriented, perhaps a little fearful, times in which the devious hand of men or the maliciousness of the devil would attempt to unsettle or mislead. . . . In New Testament times, in Book of Mormon times, and in modern times these officers form the foundation stones of the true Church, positioned around and gaining their strength from the chief cornerstone, ‘the rock of our Redeemer, who is [Jesus] Christ, the Son of God’ [Helaman 5:12 ]. . . . Such a foundation in Christ was and is always to be a protection in days ‘when the devil shall send forth his mighty winds, yea, his shafts in the whirlwind, yea, when all his hail and his mighty storm shall beat upon you.’”
