Let us not like priest or Levite coldly pass the wretched by

[Guest]

I am looking for the rest of the hymn to which one of the verses goes like this:
Let us not like priest or Levite coldly pass the wretched by
What we preach that must we practice lest our lives our lips deny
I must be my brother's keeper - prove my faith by work of love
Saved to serve be this our watchword till we join the hosts above.

The above word are how I remember them and I am not sure what the title to this song is. Is there any way you can direct me in finding this hymn? Your assistance would certainly be appreciated. Thank you.
