I came across this quote from the Puritan Richard Baxter
Let us then hear the words of Christ, whenever we feel the tendency growing in us to become dull and careless. "Did I die for them and you will not look after them? Were they worthy of my blood and yet they are not worthy of your labour? Did I come down from heaven to seek and save that which was lost, and you will not go next door or to the next street to seek after them? Compared with mine, how small is your labour and condescension. I debased myself to do this, but it is your honour to be so employed. Have I done and suffered so much for their salvation, and was I willing to make you a co-worker with me, and yet you refuse that little which lies within your hands."
