Matthew 10:42 And he who would give one of these little ones a single cup of cold water to drink in the name of a student, truly I say to you, by no means should he lose his reward.”
At Mark 9:41 it is recorded that Christ said: “For whosoever shall give you a cup of water to drink in my name, because ye belong to Christ, verily I say unto you, he shall not lose his reward.” A cup of cold water was valued in the hot dry climate of Palestine, and was a sign in itself of the restoration of life, as Christ described Himself as living water to the Samaritan woman at the well in John chapter 4. We take care of the sheep. And we are rewarded accordingly. But we have absolutely no responsibility to care for wolves, dogs and swine. And if we do, then we are neglecting sheep, and we shall suffer as much for it.
