The Wheels On The Bus

So I alight a public transport bus, which is almost full, and take the last seat. At the next stop, the doors swing open and several people climb aboard, including a friend, a member of the church, an unbeliever, a family member, a Muslim, a traveller from a distant land, a poor man and a neighbour.

A small sign on the bus says “please give up this seat to a pregnant or elderly person”.
In my culture, the rule is “first come, first served”.
Jesus said to “love thy neighbour” but loved those who were given to him.
Paul said to care for the family.
Peter said to love believers.
The evangelist says to love the unbeliever.
The missionary says to love the foreigner.

I only have one seat to give up. Who should I give it up to, if anyone?
