My theory is simple
The reason he said he can't keep a promise is that lucifers die when their child is born, right? But he's HALF Lucifer and she's HALF whatever kind of demon she is, that also has the ability to stop another demons power (I can't remember exactly what it is so forgive). So it's possible he won't die because he has a bit of human in him, like her.
End of ththeory
