3 John 1:10 For this cause, if I come, I will advertise his works which he doth; with malicious words prating against us. And as if these things were not enough for him, neither doth he himself receive the brethren, and them that do receive them he forbiddeth, and casteth out of the church.
3 John 1:11 Dearly beloved, follow not that which is evil: but that which is good. He that doth good is of God: he that doth evil hath not seen God.

3 John 1:13 I had many things to write unto thee: but I would not by ink and pen write to thee.
3 John 1:14 But I hope speedily to see thee: and we will speak mouth to mouth. Peace be to thee. Our friends salute thee. Salute the friends by name.
The verse centers on "demetrius", "testimony", "given", "truth", "thou", and "knowest". It is saying that the verse draws attention to "demetrius" and "testimony", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Dearly beloved follow not that which is..." into verse 13's "I had many things to write unto...", so "demetrius" and "testimony" belong inside that flow. In 3 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "demetrius" and "testimony" with trust shaped by these words, not by a vague optimism outside the passage.
