Do you remember paintings that have a lot of mist in them? Perhaps a seascape with a person in a rowboat? The shore is covered in mist and hardly perceptible. It's there but barely seen. You can't really see it, and yet you see a hint of it. It's there, and yet you would have to row closer to shore to see it through the mist.

This may be how you view Heaven. You wish you could get closer to it. You wish you could touch it. You wish you could peer at it through the mist.
