Mark 9:40

40 If he's not an enemy, he's an ally.

Mark 9:40 Meaning and Commentary

Mark 9:40

For he that is not against us, is on our part.
] Many copies read, "he that is not against you, is for you"; as this man; he was not against either Christ, or his disciples; he was doing the same work, promoting the same interest, and destroying the kingdom of Satan: and therefore, though he did not follow them, and had not his commission immediately from Christ; yet, inasmuch as he was opposing the same common enemy, and did nothing against them, he ought to be reckoned as one for them, and on their side. It is a proverbial expression, signifying that all that are not against a man, and take not the part of his enemy, are to be accounted his friends.

Mark 9:40 In-Context

38 John spoke up, "Teacher, we saw a man using your name to expel demons and we stopped him because he wasn't in our group."
39 Jesus wasn't pleased. "Don't stop him. No one can use my name to do something good and powerful, and in the next breath cut me down.
40 If he's not an enemy, he's an ally.
41 Why, anyone by just giving you a cup of water in my name is on our side. Count on it that God will notice.
42 "On the other hand, if you give one of these simple, childlike believers a hard time, bullying or taking advantage of their simple trust, you'll soon wish you hadn't. You'd be better off dropped in the middle of the lake with a millstone around your neck.
