Predisposed to Truth?

Maybe you have heard it too, that children don't need to be taught how to lie.

And then the thought meanders through my head, on Earth as it is in Heaven.
So will life on Earth be more like Heaven when Jesus rules the world?
Would children be predisposed to the truth?
Would it become easier to be honest and transparent than secretive and deceptive?

If we could all be more honest, what would we be saying? What would we be sharing?

Would conversation be more meaningful?
More loving?

Would we  be more sympathetic if we weren't being so guarded?
