Why is God's love so much greater?

And can there be true love without sacrifice?

There isn't sacrifice, only change. As Ra said in 18.5:

The proper role of the entity is in this density to experience all things desired, to then analyze, understand, and accept these experiences, distilling from them the love/light within them. Nothing shall be overcome. That which is not needed falls away.

There's no sacrifice, because no one truly gives up anything in terms of ideas\emotions\catalyst\etc until they aren't just ready to give it up willingly, but it's become outright unnecessary. Then it falls away as naturally as dead hairs leaving the head, or a snake shedding its skin.

A child who's finally learned to ride a two-wheeled bike isn't "sacrificing" the training wheels they previously used, right? :-)
