Mark 9:38-40
Dire Warnings
38 John said to Him, “Teacher, we saw someone casting out demons in Your name, and we tried to stop him because he was not accompanying us [as Your disciple].”(A)
39 But Jesus said, “Do not stop him; for there is no one who will perform a miracle in My name, and be able soon afterward to speak evil of Me.
40 For he who is not against us is for us.(B)
