Passage
Jesus said therefore again to them, `Verily, verily, I say to you--I am the door of the sheep;
Jesus said therefore again to them, `Verily, verily, I say to you--I am the door of the sheep;
John 10:5 and a stranger they will not follow, but will flee from him, because they have not known the voice of strangers.'
John 10:6 This similitude spake Jesus to them, and they knew not what the things were that he was speaking to them;
John 10:7 Jesus said therefore again to them, `Verily, verily, I say to you--I am the door of the sheep;
John 10:8 all, as many as came before me, are thieves and robbers, but the sheep did not hear them;
John 10:9 I am the door, through me if any one may come in, he shall be saved, and he shall come in, and go out, and find pasture.
The verse centers on "sheep", "jesus", "said", "therefore", "again", "verily", "you--i", and "door". It is saying that the verse draws attention to "sheep" and "jesus", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "This similitude spake Jesus to them and..." into verse 8's "all as many as came before me...", so "sheep" and "jesus" 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 "jesus" with trust shaped by these words, not by a vague optimism outside the passage.
