What does this Dire Straits song mean to you?

Question

Ticket to Heaven

I can see what you're looking to find
in the smile on my face
in my peace of mind
in my state of grace
I send what I can
to the man from the ministry
he's a part of heaven's plan
and he talks to me

now I send what I can to the man
with the diamond ring
he's a part of heaven's plan
and he sure can sing
now it's all I can afford
but the lord has sent me eternity
it's to save the little children
in a poor country

I got my ticket to heaven
and everlasting life
I got a ride all the way to paradise
I got my ticket to heaven
and everlasting life
all the way to paradise

now there's nothing left for luxuries
nothing left to pay my heating bill
but the good lord will provide
I know he will
so send what you can
to the man with the diamond ring
they're tuning in across the land
to hear him sing

I got my ticket to heaven
and everlasting life
all the way to paradise

Answer 1

My guess would be it is a song about people who give money to (tele)evangelists and then do not have enough for themselves.

This line I assume is a televangelist

so send what you can
to the man with the diamond ring
they're tuning in across the land
to hear him sing

Answer 2

Through doing good works, he singer feels he has attained the right to heaven and paradise, despite being poor in this life.
