1. You become exactly like them in every way (except sin)
2. You lose nothing of yourself
3. You make them become exactly like you were and now are in every way (by bearing their sin - which is the reason you'll suffer)
4. You live in one-ness with them for eternity - in the 'new' way (which is the same as the old way, but different) - the third way
