I think liking to be alive if that's what you mean, and loving the world are two different things that can be confused confused. We all like to be alive, and we can like our Christian life. We are told we can live it even more abundantly in Christ so it is clear we are to enjoy being alive.
The actual scripture does after all say it's our worldly life we should not love, not our life in Christ.
John 12:25
New International Version
Anyone who loves their life will lose it, while anyone who hates their life in this world will keep it for eternal life.
As to you not wanting Christ to return yet, I get what others are saying but there are good reasons to feel that way too...so that more can be saved, something i see was just mentioned. There may be more reasons I don't know of.
Can you tell us why you'd rather he not return at this moment?
