Faith in lord krishna

Once naradamuni was asked by a brahamana  oh, you are going to meet The Lord .will you ask him when iam going to get my salvation.
Narada agreed and proceeded he met a cobbler who was sitting under a tree mending shoes .
The cobbler too asked him the same question . He too wanted to find out about his salvation.
When narada muni went to the vaikuntha ,he fulfilled their requests and asked god about the salvation of the brahmana and cobbler.
God replied "after leaving this body the cobbler shall come here to me.
What about brahamana .? Asked narada
"He will have to remain there for a number of births .i do not know when he is comming
Narada muni was astonished and could not understand the mystery of this.
God further when you meet them next they will ask you what iam doing in my abode. You can tell them that Iam threading the eye of a needle with an Elephant
When narada returned to earth and approached the brahamana the brahmana said oh, have you seen The Lord . What was he doing. Narada replied "he was threading the eye of a needle.
the Brahmin said oh, through the eye of a needle
