Existene

Why do living entities want to continue living? 

Everyone wants to exist, even those who ultimately commit suicide. I contend that even those who elect to end their lives amid matters of honor, focus on living under certain conditions rooted in a concept of living forever memorially the way they want to be seen permanently.

Since God is Existence and is the source of all existing, one has to ask why anyone would have no hope beyond the body. The mind directs the body on a short leash, and it can be caught up in the short term demands of the body's comfort & entertainment.

So God is concerned with good and with eternal life, which was why He spoke us into existence. God cannot negate Himself, therefore only those who choose to be like Him, seek continued existence. Existence is good, but those not all those, who are spoken into existence may choose to be so directed. 

For them it would be rule or ruin. Everything God suggests is for our benefit to continue existing in the long run.
