I think it all comes down to that one word, EASIER. Nothing any more complicated than that.

I think the key part of the verses you mention occurs 2 verses later...
Matthew 19:26 But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible
+ the verse in-between!
what Christ says provokes and responds to the disciples reaction to it. understanding what he said has to fit into that context - they were blown away by this:
When the disciples heard this, they were very astonished and said,
“Then who can be saved?”
“Then who can be saved?”
so it's easier for something to occur, something which seems so impossible that it destroyed any idea the disciples had of anyone being saved.
That's the key. We can't! Not now. Not when we weren't saved. Not ever!
"but with God, all things are possible"
All of him for all of us! He is, quite literally "The Way."
