"Do the right things every day for the right reasons, and you will be just fine."

Earthly families give us the best chance to make it back to God

"Though earthly families are far from perfect, they give God’s children the best chance to be welcomed to the world with the only love on earth that comes close to what we felt in heaven—parental love. Families are also the best way to preserve and pass on moral virtues and true principles that are most likely to lead us back to God’s presence."

- President Henry B. Eyring, First Counselor in the First Presidency, "Gathering the Family of God," General Conference, April 2017

Preaching the gospel and family history work are the greatest duty

"Some individuals may wonder how both preaching the gospel and seeking after our dead can be simultaneously the greatest duties and responsibilities God has placed upon His children. My purpose is to suggest that these teachings highlight the unity and oneness of the latter-day work of salvation. Missionary work and family history and temple work are complementary and interrelated aspects of one great work, “that in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him” (Ephesians 1:10)."

God will save all who are determined to be saved

"Let those apostatize who wish to, but God will save all who are determined to be saved (DBY, 86)."

Every trial and experience you have passed through is necessary for your salvation

“All intelligent beings who are crowned with crowns of glory, immortality, and eternal lives must pass through every ordeal appointed for intelligent beings to pass through, to gain their glory and exaltation. Every calamity that can come upon mortal beings will be suffered to come upon the few, to prepare them to enjoy the presence of the Lord. … Every trial and experience you have passed through is necessary for your salvation.”
