2 John 10-11

v10: How should we respond to those preachers whose teaching is deceptive? We must not support them, nor encourage them in their work, because they “destroy people’s souls” by what they say. We must not approve of what they are doing or give their service our prayers. “Bad work should not be commended… to God’s blessing.”

v11: “It is possible to share in the sins of others,” and one of the ways we do that is by giving approval and encouragement to false teachers, whether this be “blameworthy silence, laziness, neglect, private contributions, public support and help, inner approval, and open defence.”
