Comentators try to tone down Paul’s statement, explain that Luke and others must have been off on missions of their own—and they may well have been—that Paul is making a general statement about the world. The statement continues to be no less shocking.
All of them are seeking their own interests, not those of Jesus Christ.
Philippians 2.21 NRSV
Timothy alone had genuine concern for the Philippians’ welfare. No one else.
Would Paul change his statement if he were writing today?
So who among us will be the Timothy for our day?
