1 Nephi 15:14

and at that day, shall the remnant of our seed know that they are of the House of Israel, and that they are the covenant people of the Lord; and then shall they know and come to the knowledge of their forefathers, and also to the knowledge of the Gospel of their Redeemer, which was ministered unto their fathers by him; wherefore, they shall come to the knowledge of their Redeemer, and the very points of his doctrine, that they may know how to come unto him and be saved.

At that day, the remnant of our descendants will know they are from the House of Israel and are God’s covenant people. Then they will learn about their forefathers and the gospel of their Redeemer, which was taught to their fathers by him. So they will learn about their Redeemer and the exact points of his teaching, so they may know how to come to him and be saved.

“When that day comes, our descendants will realize they’re part of Israel, God’s covenant people. They’ll learn about their ancestors and understand the gospel their Redeemer taught. They’ll know exactly how to come to him and be saved.”
