Passage
All that ever came before me are thieves and robbers: but the sheep did not hear them.
All that ever came before me are thieves and robbers: but the sheep did not hear them.
John 10:6 This parable spake Jesus unto them: but they understood not what things they were which he spake unto them.
John 10:7 Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.
John 10:8 All that ever came before me are thieves and robbers: but the sheep did not hear them.
John 10:9 I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
John 10:10 The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
The verse centers on "sheep", "ever", "came", "before", "thieves", "robbers", and "hear". It is saying that the verse draws attention to "sheep" and "ever", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "Then said Jesus unto them again Verily..." into verse 9's "I am the door by me if...", so "sheep" and "ever" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "sheep" and "ever" with trust shaped by these words, not by a vague optimism outside the passage.
