Docrine & Covenants 76:22-24
22. And now, after the many testimonies which have been given of him, this is the testimony, last of all which we give of him: That he lives!
23. For we saw him, even on the right hand of God; and we heard the voice bearing record that he is the Only Begotten of the Father--
24. That by him, and through him, and of him, the worlds are and were created, and the inhabitants thereof are begotten sons and daughters unto God.
