A cup of cold water!
"And if anyone gives even a cup of cold water to one of these little ones because he is My disciple, I tell you the truth, he will certainly not lose his reward!" Matthew 10:42
Well, I can do as much as that. I can do a kind act toward the Lord's servant. The Lord knows I love them all, and would count it an honor to wash their feet. For the sake of their Master — I love the disciples.
How gracious of the Lord to mention so insignificant an action — even a cup of cold water! This I can do, however poor; this I may do, however lowly; this I will do cheerfully. This, which seems so little, the Lord notices — notices when done to the least of His followers.
Evidently it is not the cost, nor the skill, nor the quantity, that He looks at — but the motive. That which we do to His disciple, because he is His disciple — the Lord observes, and recompenses. He does not reward us for the merit of what we do — but according to the riches of His grace. I give a cup of cold water — and He makes me to drink of living water. I give to one of His little ones — and He treats me as one of them. Jesus finds an apology for His liberality, in that which His grace has led me to do, and He says, "He will certainly not lose his reward!"
"I tell you the truth, whatever you did for one of the least of these brothers of Mine — you did for Me!" Matthew 25:40
