Passage
For whosoever shall give you to drink a cup of water in my name, because you belong to Christ: amen I say to you, he shall not lose his reward.
For whosoever shall give you to drink a cup of water in my name, because you belong to Christ: amen I say to you, he shall not lose his reward.
Mark 9:38 But Jesus said: Do not forbid him. For there is no man that doth a miracle in my name and can soon speak ill of me.
Mark 9:39 For he that is not against you is for you.
Mark 9:40 For whosoever shall give you to drink a cup of water in my name, because you belong to Christ: amen I say to you, he shall not lose his reward.
Mark 9:41 And whosoever shall scandalize one of these little ones that believe in me: it were better for him that a millstone were hanged about his neck and he were cast into the sea.
Mark 9:42 And if thy hand scandalize thee, cut it off: it is better for thee to enter into life, maimed, than having two hands to go into hell, into unquenchable fire:
The verse centers on "whosoever", "shall", "give", "drink", "water", "name", "belong", and "christ". It is saying that the verse draws attention to "whosoever" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 39's "For he that is not against you..." into verse 41's "And whosoever shall scandalize one of these...", so "whosoever" and "shall" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "whosoever" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
