For a discussion of what Jesus meant when He said, “I do not destroy the prophets” (3 Nephi 15:6), see commentary for 3 Nephi 12:17–20, 46–47 (page 305).
What did Jesus mean when He said, “The covenant which I have made with my people is not all fulfilled”? (3 Nephi 15:8). Jehovah made a covenant with Abraham anciently. Abraham was promised (1) eternal posterity, (2) a land that would eventually be the celestial kingdom, and (3) God’s priesthood power. These promises were also made to Abraham’s descendants (see D&C 132:30–31) and will be fulfilled in the future.
