Passage
For he that saith unto him: God speed you, communicateth with his wicked works.
For he that saith unto him: God speed you, communicateth with his wicked works.
2 John 1:9 Whosoever revolteth and continueth not in the doctrine of Christ hath not God. He that continueth in the doctrine, the same hath both the Father and the Son.
2 John 1:10 If any man come to you and bring not this doctrine, receive him not into the house nor say to him: God speed you.
2 John 1:11 For he that saith unto him: God speed you, communicateth with his wicked works.
2 John 1:12 Having more things to write unto you, I would not by paper and ink: for I hope that I shall be with you and speak face to face, that your joy may be full.
2 John 1:13 The children of thy sister Elect salute thee.
The verse centers on "saith", "speed", "communicateth", "wicked", and "works". It is saying that the verse draws attention to "saith" and "speed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "If any man come to you and..." into verse 12's "Having more things to write unto you...", so "saith" and "speed" belong inside that flow. In 2 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "saith" and "speed" with trust shaped by these words, not by a vague optimism outside the passage.
