This 'consolation poem' bothers me

I have seen this phrase, from a poem, on various things that are supposed to console the ones of those who are still on earth after their loved one passed on.  While I understand that the poem is to talk of how much the loved one is missed on earth, if you truly believe in Heaven, why in the WORLD would you want to 'bring them back again'?

If tears could build a stairway, 

and memories a lane.

I would walk right up to Heaven

and bring you back again.
