Mark 9:41

41 If anyone gives you even a cup of water because you belong to the Messiah, I tell you the truth, that person will surely be rewarded.

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 “Don’t stop him!” Jesus said. “No one who performs a miracle in my name will soon be able to speak evil of me.

40 Anyone who is not against us is for us.

41 If anyone gives you even a cup of water because you belong to the Messiah, I tell you the truth, that person will surely be rewarded.

42 “But if you cause one of these little ones who trusts in me to fall into sin, it would be better for you to be thrown into the sea with a large millstone hung around your neck.

43 If your hand causes you to sin, cut it off. It’s better to enter eternal life with only one hand than to go into the unquenchable fires of hell with two hands.
