Wishing is the beginning of imagination. They practice wishing when they are young things, and then -when they have grown - they have a developed imagination. Which can do some harm - greed, that kind of thing - but more often does them some good. They can imagine that things might be different. Might be other than they seem. Could be better.
Choosing one thing over another doesn't necessarily mean we love the thing we choose. If given the choice to eat spinach or broccoli, you may choose broccoli. It may only mean you don't want to eat spinach. Heaven is not for people who just want to skip Hell. Heaven is reserved for those who love Jesus, who have been rescued by Him and who long to praise Him. If someone doesn't have much use for praising Him now, it's foolish to think they're ready for Heaven.
