Why doesn't the match function work if the list is out-of-order?

Is there a function that will find the FIRST VALUE IN A LIST (EVEN IF
IT IS OUT-OF-ORDER) that is the smallest value greater than or equal
to the specified value?

For example, given in cells A1:A4:

2
3
5
1

How do I ask for the first value that comes along that is greater than
or equal to 4? So that the return value would be "3" since 5 is in
the "3"-position of the list.
