Passage
Marvel not, brethren, if the world hateth you.
Marvel not, brethren, if the world hateth you.
1 John 3:11 For this is the message which ye heard from the beginning, that we should love one another:
1 John 3:12 not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother`s righteous.
1 John 3:13 Marvel not, brethren, if the world hateth you.
1 John 3:14 We know that we have passed out of death into life, because we love the brethren. He that loveth not abideth in death.
1 John 3:15 Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
The verse centers on "world", "marvel", "brethren", and "hateth". It is saying that the verse draws attention to "world" and "marvel", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "not as Cain was of the evil..." into verse 14's "We know that we have passed out...", so "world" and "marvel" belong inside that flow. In 1 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "world" and "marvel" with trust shaped by these words, not by a vague optimism outside the passage.
