Jesus Christ
Behold, I am God; give heed to my word, which is quick and powerful, sharper than a two-edged sword, to the dividing asunder of both joints and marrow; therefore give heed unto my word. Doctrine and Covenants 11:2
The speaker who says 'I am God' here is the one who says 'I am Jesus Christ' in verse 28. He describes His own word with the image Hebrews uses for the word of God.
How we know: the verse itself names Him · the chapter heading names Him
- alludes to Hebrews 4:12 — the word of God quick, powerful, sharper than a two-edged sword
- the same title in D&C 11:28 — the same speaker names Himself Jesus Christ
