Mosiah 15:13

Yea, and are not the prophets, every one that has opened his mouth to prophesy, that has not fallen into transgression; I mean all the Holy Prophets ever since the world began; I say unto you that they are his seed;

All the prophets who spoke God’s message are his children too. I mean all the holy prophets since the world began who didn’t sin. I say they are his children.

And what about the prophets—every one who spoke God’s message and stayed faithful? I mean all the holy prophets since the world began. They’re his children too.
