Well, there's this:

Lord give me a burden for souls,
Give me a burden for souls,
Open my eyes, help me realize,
That right now it is harvest time.
Lord give me a burden for souls,
Give me a burden for souls,
Help me to care, help me to share,
Lord give me a burden, yes I need a burden,
Please give me a burden for souls.
(Song by Dale R. Starks)

A Google search for "give me a burden" (in quotes) brings up lots of stuff. I take it that it's some kind of evangelical buzzword - which makes for a pritty big haystack in which to find your needle.
