Passage
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
John 10:14 I am the good shepherd, and know my sheep, and am known of mine.
John 10:15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
John 10:16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
John 10:17 Therefore doth my Father love me, because I lay down my life, that I might take it again.
John 10:18 No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
The verse centers on "sheep", "other", "fold", "must", "bring", "shall", "hear", and "voice". It is saying that the verse draws attention to "sheep" and "other", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "As the Father knoweth me even so..." into verse 17's "Therefore doth my Father love me because...", so "sheep" and "other" 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 "other" with trust shaped by these words, not by a vague optimism outside the passage.
