Indeed, if anyone gives you even a cup of water because you bear the name of Christ, truly I tell you, he will never lose his reward.
Here, I. Christ promiseth a reward to all those that are any way kind to his disciples (Mar 9:41); "Whosoever shall give you a cup of water, when you need it, and will be a refreshment to you, because ye belong to Christ, and are of his family, he shall not lose his reward." Note, 1.
Commenting on Mark 9:41-50
And whosoever shall offend one of these little ones that believe in me,.... Whosoever shall do the, least injury to the meanest person that believes in Christ, who are mean both in their own eyes, and the eyes of others; for Christ is not speaking of little children in age, who are neither capable of believing in Christ, nor are they ready to take offence...
Verse 41. Whosoever shall give you a cup, etc. How easy it is to be a Christian! What is easier than to give a cup of cold water to a thirsty disciple of Jesus! But it must be in his name--that is, because he is a Christian, and therefore from love to the Saviour. This is very different from giving it from a mere motive of common kindness.
