Mark 9:41 Meaning and Commentary

Mark 9:41

For whosoever shall give you a cup of water to drink
Not only one that does a miracle in the name of Christ, but he that shows the least respect, or does the least kindness to any one of his; (See Gill on Matthew 10:42); is to be reckoned a friend, and is so accounted by Christ; and will be sooner or later taken notice of by him, especially, if what he does, be it ever so little, is done on his account:

in my name, because ye belong to Christ;
or as the Syriac version renders it, "on account that ye are Christ's"; are his disciples, are called by his name, are partakers of his grace, bear his image and likeness, are loved by him, interested in him, given to him, redeemed by him called by his grace, and shall be with him:

verily l say unto you, he shall not lose his reward;
(See Gill on Matthew 10:42).

Mark 9:41 In-Context

39 But Jesus said, "Do not prevent him, because there is no one who does a miracle in my name and will be able soon afterward to speak evil of me.

40 For whoever is not against us is for us.

41 For whoever gives you a cup of water to drink in [my] name because you are Christ's, truly I say to you that he will never lose his reward.

42 "And whoever causes one of these little ones who believe in me to sin, it is better for him if instead {a large millstone} is placed around his neck and he is thrown into the sea.

43 And if your hand causes you to sin, cut it off! It is better [for] you to enter into life crippled than, having two hands, to go into hell--into the unquenchable fire!
