Mark9:38 9 John said to him, “Teacher, we saw someone driving out demons in your name, and we tried to prevent him because he does not follow us.”
39 Jesus replied, "Do not prevent him. There is no one who performs a mighty deed in my name who can at the same time speak ill of me.
40 For whoever is not against us is for us.
41 Anyone who gives you a cup of water to drink because you belong to Christ, amen, I say to you, will surely not lose his reward.
footnote9 [38-41] Jesus warns against jealousy and intolerance toward others, such as exorcists who do not follow us. The saying in Mark 9:40 is a broad principle of the divine tolerance. Even the smallest courtesies shown to those who teach in Jesus’ name do not go unrewarded.
John 10:14 I am the good shepherd, and I know mine and mine know me,
15 just as the Father knows me and I know the Father; and I will lay down my life for the sheep.
16 I have other sheep 7 that do not belong to this fold. These also I must lead, and they will hear my voice, and there will be one flock, one shepherd.
footnote
7 [16] Other sheep: the Gentiles, possibly a reference to “God’s dispersed children” of John 11:52 destined to be gathered into one, or “apostolic Christians” at odds with the community of the beloved disciple.
